End of Back To The Future Day

Back to the Future Day filled with nostalgia - and jokes

When Marty McFly travelled to the future in the 1989 "Back to the Future" sequel - to October 21, 2015, to be precise - he was greeted by flying cars, self-tying sneakers and hovering skateboards.

The futuristic items were from a distant world for the time-travelling teenager on a journey from 1985 to 2015 to save his children.

But that day finally arrived on Wednesday, dubbed "Back to the Future Day" as fans of the blockbuster trilogy around the world celebrated the movie milestone.

At the Houston, Texas headquarters of DeLorean cars, whose gull-winged DMC-12 model was adapted in the film into a time machine, crowds gathered to mark the anniversary.

Doc Brown is seen holding a tablet in Back to the Future II

"A lot of people are getting their cameras out and taking pictures," DeLorean Motor Co CEO Stephen Wynne told reporters. "When we opened... at 8 o'clock this morning, a woman ran in and she was dressed as Marty McFly and everybody goes, 'whoa'!"

In Canada, a playful recall announcement on the official Health Canada website said that "a certain DMC-12 car converted into a time machine, a defect in the flux capacitor could lead to inability to travel through time. Doc Brown will affect repairs."

One short scene has US baseball fans abuzz. A holographic news board informs Marty McFly that the long-suffering Chicago Cubs have won the 2015 World Series.

The Cubs actually made it to the Major League Baseball playoffs this year, and it seemed like the scene might be prescient. But now the Cubs are one loss away from being eliminated from contention by the New York Mets, which would continue the Cubs' 107-year championship drought.

While the so-called hover boards have yet to make their commercial debut, other gadgets such as wearable eye glass screens and video calls have turned out closer to the mark.

"We've got 3D movies," Lloyd says as the two actors sit in a diner. "We've got fingerprint technology," Fox answers.

Pepsi unveiled a limited run of "Pepsi Perfect", the soda McFly drinks in the film, while Nike, whose power-laced shoes the character wore, tweeted Fox on Tuesday saying "See you tomorrow", leaving fans speculating over the message.

Some fans had hoped for a revival of the franchise at a time when others movies are getting reboots. But earlier this week, one of the films' executive producers said a fourth instalment was unlikely.

00.29 - How the day played out. Was it as predicted in 1985?

Back to the Future Day is over. The exact time Marty and Doc Brown travel forward to from 1985 - has been and gone. This time round.

00.08 Driver in silver DeLorean stopped doing 88mph

Michigan state police join in fun of Back to the Future Day, claiming they stopped two speeding drivers called Dr Emmett Brown and Marty McFly going at 88mph in a DeLorean.

The police wrote: "Michigan State Police troopers stopped a silver DeLorean today for driving 88mph in a 55mph zone.

"The two occupants, Dr Emmett Brown and Marty McFly, were given a verbal warning to drive more safely on Michigan roads. Dr Emmett Brown responded by saying, 'Roads? Where we’re going, we don’t need roads.'”

The Canadian government also joined in the fun, releasing an official recall notice on the DMC-12 model DeLorean.

“On a certain DMC-12 car converted into a time machine, a defect in the flux capacitor could lead to inability to travel through time while travelling at 88 miles per hour (141.6km/h) and may increase energy consumption beyond 1.21 gigawatts,” the spoof statement said, referring to the speed at which the films' DeLorean can travel to the future. “This could have disastrous consequences.”

Christopher Lloyd has given an interview to Vulture.com about Back to the Future Day. He says he's surprised by all of today's excitement:

"I didn't imagine that 30 years later, there'd be this enthusiasm and excitement about it. This celebration, I didn't see that coming at all. Back to the Future came out, and there was a two-year lapse, and we did II and III together. We were just making another movie and hoping it gets past opening night. But the kids who saw this film, they've grown up and had kids, who have grown up and had kids. It's exponential, it just keeps spreading out more and more. But the film has aged well. I saw it last night. It seems very contemporary."

22.23

Even the leader of the free world is getting in on the excitement generated by Back to the Future Day:

Couple tie the knot with Back to the Future themed wedding on Back to the Future Day:

Jordan Gillard, 26 and Sally Evans, 24, from Pontypridd are massive fans of the film, so after Jordan got down on one knee and proposed last year they knew a themed wedding would be on the cards.

Sally said: "Jordan and I have been together for around 10 years and we'd always talked about having a Back to the Future themed wedding. So when he proposed we knew we'd stick to the idea.

"We're kind of 'mega nerds' about the film, so when we knew Back to the Future Day was coming up this year we planned everything around that."

The couple started the plans earlier this year by sending out invitations, which were in the form of a letter that Marty wrote to Doc in the film.

"We'd been planning it for a while and we had lots of bits and pieces to go with the theme," Sally said.

"Our table plans were organised around different places Marty and Doc visited in '2015', we also have a 'Hill Valley' sign we painted ourselves to go outside the venue and the ceremony music was the orchestral version of the sound track."

Sally arrived at the wedding, which was held at De Courceys Manor in Pentyrch, in a Buick, a car which was used in the film. While Jordan 'time travelled' to the venue in a DeLorean, the car which Doc Brown used as his vehicle of choice for travelling through time.

Here's the third in our series (oh for God's sake – Ed) of original Back to the Future reviews. This one from John Coldstream, published in 1990, is a review of Back to the Future III and applauds "a wholly delightful excursion, in the hands of some master craftsmen who have recaptured the spirit that made the first of the series so appealing."

This one from Hugo Davenport, published in 1989, is a review of Back to the Future II and it says: "The film is full of sparky, inventive jokes and some special effects (the anti-gravity skateboards stand out) that will amze even the most blase young video-sophisticate."

Trust Microsoft to be one step ahead of everyone else. But I like this... it's a look at what the world will be like in 2045, 30 years from now (the same jump forward in time taken by Marty and Doc in Back to the Future 2).

Here are their thoughts:

1. Artificial Intelligence

Futurist Ray Kurzweil said that it was perfectly reasonable to expect computers to exhibit human-level intelligence and emotions within the next 15 years. So in 30 years, expect to see AI intelligence presented as a virtual presence that you can see and potentially feel.

2. A 'Smart' City

We're still at very early stages for the Internet of Things (IoT), but we are already seeing connected devices such as the Microsoft Band. In 2045, expect to live in cities where everything could be connected. You may well be regularly talking to your fridge, cooker or thermostat!

3. Robots

Robots can already be used for demanding and repetitive tasks not suitable for humans. Imagine a world of connected robots communicating together, monitoring events, controlling and manipulating physical objects. Do you want a robot buddy to hang out with? Maybe one that could serve you drinks?

4. Self-driving Cars

There are already a number of tech companies currently working on this. In 30 years, expect it to be a reality where people call for a taxi without a driver, which drives itself to the venue of your choice, which you pay for on your hand-held device. Will we be still using smartphones?

5. Mixed Reality

We've started the age of the HoloLens. Where will this technology be in 30 years? Imagine going to a fashion retailer and experience a shopping experience where you can try on different clothes with a pair of augmented reality goggles? Or play video games using 3D images without the use of a screen...

Thanks, Microsoft. And what will future generations discover if and when they travel back in time?

We can confirm that ITV2 did cut parts of Back to the Future. And with f-----g good reason.

Back to the, er, past. Our peerless archivist Gavin Fuller has dug up the original Telegraph review of Back to the Future and it's a rather wonderful thing.

Eric Shorter wrote in 1985: "It restores your faith in the fun to be mined from a time machine because it is well written, wittily conceived, tautly plotted and once its premise has been granted, as in all good farce, it proceeds with unerring logic to develop its absurdity with a proper, frenzied sense of seriousness."

17.20

The Back to the Future marathon is well underway on ITV2 (it started at 4.29 *bravo*). But one fan ain't happy. Can anyone confirm whether this is true? Tweet me @ruhawksley

My colleague Mark Monahan assures me that this is essential background reading for any Back to the Future fan. Yes, it's his review of the original film.

"This fusion of sci-fi, action, romance and comedy could have been a dreadful mess, were it not for writer-director Robert Zemeckis and co-writer Bob Gale's refusal to let a loose line or idea escape their pens."

If that hasn't put you off, read the lot here.

Speaking of the DeLorean, this is a lovely piece by Andrew Frankel on how the film's automotive star has stood the test of time.

"The Department of Transtemporal Studies at Leicester (formerly the School of Anomalous Chronography) was founded in 1985. We are a leading centre for research and teaching into all aspects of time travel.

"Staff in the Department have extensive experience of journeying to a wide variety of historical and future periods, using a range of techniques. We have a comprehensive selection of state-of-the-art time machines, ranging in size from multi-person vehicles to individual wristbands, which are used for teaching our degrees and also for research at the cutting edge of chronolysis and chronography.

Here are some odds from Paddy Power on what will happen in 2045

"The bookmaker has jumped in his handy time machine to offer 2/1 for Police to be using hover boards, while it’s a futuristic 4/1 for Domestic Robots to be used at Buckingham Palace.

"Paddy might sound like he’s from Planet Vulcan, but the bookie is even offering just 9/4 for England to have won the football World Cup by 2045.

2045 UK Predictions

• 2/1: Hoverboards to be used by police officers

• 4/1: Domestic Robots to be in use at Buckingham Palace

• 9/4: England to have won a football World Cup

• 4/11: Labour to have won a majority in a general election

Austria legalises hoverboards just in time for Back to the Future day

Justin Huggler reports from Berlin:

You can now legally use a hover-board on the streets in Austria – in the unlikely event you can get your hands on one.

In a bizarre homage to the Back to the Future film trilogy, the Austrian ministry of transport has made an official ruling that hover-boards are street-legal.

The announcement was timed for today’s date, October 21, 2015 – the date Marty McFly travels to the future in the films and first encounters a hover-board.

You can now use a hover-board on Austrian roads and pavements without any special license or permit.

The only problem is that the films’ prediction of levitating teenagers was slightly off.

Genuine hover-boards which float above the road surface are not yet commercially available.

However, several manufacturers are working on prototypes, and no one could accuse the Austrian authorities of being unprepared.

The ministry of transport says hover-boards are legal “anywhere you could go with an old-style skateboard” in an official announcement on its website.

“It is important that you don’t obstruct traffic or pedestrians,” the announcement says.

But the ministry warns that because of its ability to travel in different terrains, a hover-board could also be “considered an aircraft”.

“Depending on where you're traveling with your hover-board (water, soil, air), different rules may apply,” it says.

The ministray says the use of a handlebar, as seen in the film, is not a problem.

But it says anyone wanting to use the rocket-powered “Pit Bull” hover-board depicted in the film would need a pilot’s license.

The website also warns hover-boarders: “It’s always a good idea to wear a helmet for your own safety when riding.”

Six experts predict what life will be like in 2045

Will they be better at predicting what the future is like than Back to the Future? They've told James Titcomb and Madhumita Murgia from the Technology desk what we should expect in thirty years time.

Predictions include the ability to buy emotions online, invisibility cloaks, artificial intelligence and virtual reality.

Train station banter:

The spoilsports at South West trains have reminded passengers that they are not allowed to use hoverboards or time travel while using their service.

It seems like wherever you go today, you'll see tepid Back to the Future jokes, including on this live blog!

What a glorious occasion!

It must be a bit confusing for those who have not watched the film.

Apparently Back to the Future Day is going on until tomorrow morning. It is unclear whether livebloggers will be expected to sit at their computers until then (a source says that she hopes that isn't the case).

Back To The Future Day is tomorrow (Marty and Doc arrived in Hill Valley at 4.29pm Pacific Time, which is 0.29am British Summer Time) — diamond geezer (@diamondgeezer) October 21, 2015

This tweeter has pointed it out, apparently they actually went Back to the Future after midnight UK time.

Oh, and luckily for us, the DWP have chipped in with some 'banter' which is sure to make all of their many fans amused.

They wrote: ‘Pensions? Where we’re going we don’t need pensions…’ #DontIgnoreIt #BackToTheFuture http://www.workplacepensions.gov.uk/ "

And then on their image, they put "Erm, actually you do."

It's a bit of a weird joke.

Protesters park a DeLorean outside Parliament to protest the fact that hoverboards are illegal

Hoverboards have been made illegal to ride in public, along with Segways, and this has annoyed some fans of innovation.

We've received a press release from Project 42, who manufacture hoverboards.

Naturally, they are annoyed about the ban so they are parking a DeLorean outside Parliament and will have a Marty McFly lookalike on a modern day hoverboard.

Here is what they said:

"21st October 2015. That’s the date Marty McFly travelled 30 years into the future at the end of “Back to the Future.” He arrived in a world where a can of Pepsi costs $50 and where hoverboards were on every street corner.

"Today, Pepsi remains affordable but the dream of hoverboards seems further away than ever despite thousands of British consumers purchasing the self-balancing devices. On Sunday last week the Crown Prosecution Service (CPS) outlawed ‘hoverboards’ and other self-balancing vehicles due to a law that was made in the 1835 Highways Act, 180 years ago!

"Project 42 (P42), a UK accelerator behind the UniWheel, one of the self-balancing products, has arranged for a genuine DeLorean to descend on the Houses of Parliament to highlight how this archaic law could stifle tech and innovative products that were once a dream. With the technology developing so quickly, only now has it become clear that this law will prevent people in the UK from experiencing their dreams and riding hoverboards."

Back to the Future: Its enduring appeal, and why it should never be remade

The University of Leicester has analysed the appeal of Back to the Future and has argued that it should never be remade (especially, perhaps, by Keith Lemon...)

Here's a snippet:

"In recent years, following the film’s cinema re-release for its 25th anniversary, Secret Cinema’s highly acclaimed immersive screenings of the first film, and technological developments such as Lexus’ hoverboard inspired by the films, the appeal of Back to the Future seems to be increasing. Perhaps this is because nostalgia for the film and its characters has not been affected by attempts to remake or re-boot the series. Unlike many other popular franchises of the 1980s such as Indiana Jones or Ghostbusters there are no plans to remake or extend the Back to the Future series.

"In fact its creators are set against the idea of a remake, with director Robert Zemeckis saying it could not happen until he and the film’s writer, Bob Gale, are dead – and hopefully not even then. In a rather grandiose claim, Zemeckis argued it would be like remaking Citizen Kane asking ‘What folly? What insanity is that?’ (Collins, 2015). But is he wrong to compare Back to the Future to, what is often thought of as, the greatest film of all time?"

07.00 What's the plot?

Dr Emmett Brown takes Marty and his girlfriend Jennifer to the future to prevent their kids from "ruining their lives".

After doing that, Marty buys a sports almanac for 1950-2000, thinking it might help him in his time. Doc finds out and throws it away, but 2015 Biff (now a very old man) finds the book and uses the DeLorean to give the almanac to his younger self.

When Marty and Jennifer arrive back to their own time, they find it has totally changed - Biff is very rich and practically owns the city, (sound familiar?). He is married Marty's mother, killed his dad, and when Marty starts to ask about the almanac, he wants to kill him too.

Doc also finds out that he was imprisoned in an asylum, so the two go back to 1955, the night of the Enchantment-Under-The-Sea party in an effort to take back the almanac.

What did 'Back to the Future II' get right about 2015?

Big-screen televisions and video calls

The film features several scenes of characters watching screens very much like the oversize ones we actually use these days. That's saying something, because most TVs of the 1980s were heavy, square appliances with bulky picture tubes. Some of them even came in wood-grain cabinets like furniture!

Also, the "BTTF II" characters talk to the screens just like we do today. Not bad, given that videophones -- though long promised -- barely existed in 1989. With FaceTime and Skype now staples, the video call has evolved from a business medium to an essential of everyday life.

Earlier this year, Canadian inventor Catalin Alexandru Duru broke the world record for the longest hoverboard flight, standing on the back of a Omni Hoverboard, his homemade, propeller-powered vehicle. With its downward-thrusting propellers, powered by a dozen lithium polymer batteries, it looks like a military drone and floats like a giant swimming aid with a man on top.

In May, Duru flew his patent-pending piece of kit at a height of 16ft above a Quebec lake, for 300 yards, on a trip that lasted a minute and a half.

Duru is not the only engineer who believes we can fly. A California company used Kickstarter money to develop the Hendo Hoverboard, which uses electromagnets to zip above a metal floor, while car manufacturer Lexus recently unveiled a wheelless skateboard made from bamboo and carbon fibre fitted with a superconductor cooled by liquid nitrogen to enable it to levitate above magnetic flooring.

To celebrate the date Marty McFly arrived in the future, an advert for the ‘Hover master’ has been made by Universal.

Video glasses

The Back to the Future films also presaged wearable technology, such as wraparound glasses which Marty uses to answer and speak on the phone (Google Glass, anyone?). Microsoft's recently announced Hololens bears more then a passing resemblence to Junior's goggles.As Doc might say: “Great Scott!”

Self-tying shoes

Nike is promising to develop hi-top trainers with inbuilt motors so the laces do the hard work by themselves.

While we’re no nearer to a flying car than when the film was released in 1989, it got some things right. Biff, one of the series’ main characters, pays for a taxi ride with a thumb print – just like the fingerprint technology used on the iPhone 6 and cashless apps such as Uber, Hailo and Bounce.

Jaws 19 trailer has actually been released

he scene in Robert Zemeckis' Back to the Future II, released in 1989, when Marty McFly travels in his DeLorean to 2015? In the background, a cinema is advertising Jaws 19. It is an amusing detail; a sly dig at the increasing absursity of the (never-ending) Jaws sequels. But it could never really happen... could it?

What did Back to the Future II get wrong?

Flying cars powered by rubbish

We're not quite at the stage of seeing cars zip through the air - although this guy has given it a good go... And fossil fuels still power our cars despite electric making inroads. What price a flux capacitor. Can someone get Elon Musk on the video phone..?

Power clothing

Now this is one thing we wish 2015 had brought: jackets that dry themselves and shoes that lace themselves up. Look, no hands!

Fax machines

The film went a little too heavy on its predictions for fax machines, which it imagined would be everywhere in 2015. Fortunately, they're not

... And there's one key invention Back to the Future II missed out: smartphones and tablets, undeniably the most important technological breakthrough of the last decade. Apple didn't even get a look-in.

Might have come in handy when Marty and the Doc wanted to escape the future and head back to 1985.

06.45: It's here - at last!

Hello and welcome to our Back to the Future liveblog on October 21, 2015 - the date that Marty McFly and Dr Emmett “Doc” Brown chose to travel forward in time from 1985 in the hit sequel Back To The Future II.

According to the time-bending 1980s sci-fi flick, by October 21 2015, we would be living in a world of hoverboards, flying cars and self-tying shoelaces. And now that the day has actually arrived.
