Filmmaker James Cameron, forever an advocate for the 3D format, wants to push things one step further with his Avatar sequels (all four of them).

He's hoping that you'll be able to watch them - well, some of them at least - in 3D without having to don a pair of glasses.

The director was giving a speech at the Society of Motion Picture and Television engineers when he made the statement.

He said: "I’m going to push. Not only for better tools, workflow, high dynamic range (HDR) and high frame rates (HFR) - the things we are working toward… I’m still very bullish on 3D, but we need brighter projection, and ultimately I think it can happen - with no glasses. We’ll get there."

Glasses-free 3D has not yet been pioneered for use in cinema, however, the technology is available on Nintendo 3DS. The use of cinematic 3D has advanced quite far since its impressive deployment in Cameron's Avatar which was released in 2009.

Having been hard at work on its 'overwritten' sequels (his words) for six years now, it seems Cameron is using the world of Pandora and its Na'vi inhabitants to further the experience. The sequels are said to follow Jake (Sam Worthington) Neytiri (Zoe Saldana) and their children's "battle with humans."

Avengers: Age of Ultron After the brilliant first Avengers, Age of Ultron had a lot to live up to. Reuniting the team wouldn’t be enough, they needed a worthy adversary. Unfortunately, with Joss Whedon trying to ram so many superheroes on screen at once, the result was not as polished nor as fun as its predecessor. Marvel Highest-grossing films of all time - ranked 9. Furious 7 One of the best films in the Fast and Furious franchise, Furious 7 features Paul Walker’s final performance on film. The all-thrills sequel was a surprisingly massive hit, with Vin Diesel since announcing another three films. Highest-grossing films of all time - ranked 8. Harry Potter and the Deathly Hallow - Part 2 The final part in the epic Harry Potter saga was an emotional time for many: It would be the last time Daniel Radcliffe would have the iconic lightning bolt scar painted to his forehead. For that one reason, it was always going to be a success. Unfortunately, splitting JK Rowling’s final novel in two probably wasn’t the greatest idea, leading to one of the weakest entries in an all round great series. Highest-grossing films of all time - ranked 7. Iron Man 3 Coming straight off the back of Avengers, Iron Man 3 gave Robert Downey Jnr’s character PTSD, shoved in a protege, and made iconic villain The Mandarin a phoney. Some fans were not pleased while others thoroughly enjoyed the film. For Marvel fans, however, the third instalment in the Iron Man series is either one of the most hated MCU films or one of the greatest. Marvel Highest-grossing films of all time - ranked 6. Jurassic World Coming out 22 years after Jurassic Park, World was a fast paced action film that bombastically ran everyone through the new park. Chris Pratt’s performance was enjoyed by many, but the spectacle of dinosaurs on screen wasn’t quite as thrilling fourth time around. Highest-grossing films of all time - ranked 5. Frozen “Let it go, let it go!”, “Do you wanna build a snowman?” and “Love is an open doooooooooooor”. There, those should be in your head for a little while now. Disney managed to make a Christmas classic that won the hearts of children and adults alike with Frozen, making The Mouse millions in the process. Highest-grossing films of all time - ranked 4. Avatar The highest grossing film on the list, and for good reason. For many, Avatar was their first 3D cinematic experience, leaving people in awe of the spectacle they just witnessed. Hundreds went back multiple times (including myself), but many have forgotten about the once wonderful film. Whether it would make as much money today, now that every other film is in 3D, would be very, very interesting. Highest-grossing films of all time - ranked 3. Avengers Joss Whedon’s fist attempt at bringing together Captain America, Iron Man, Thor and The Hulk was masterfully executed. An action-packed romp featuring good guys v bad - what was not to love? Highest-grossing films of all time - ranked 2. Star Wars: The Force Awakens Joss Whedon’s fist attempt at bringing together Captain America, Iron Man, Thor and The Hulk was masterfully executed.

Titanic It was a close toss-up between Star Wars and Titanic for best 'highest-grossing film' movie, but the disaster film edged it. Cameron’s classic set a new precedent in 1997 for just how much money films could make, and it wasn’t until his return to cinema with Avatar that the record was broken again. It was also a critical success and, importantly, launched Leonardo DiCaprio and Kate Winslet into the spotlight.

On the other end of the spectrum is director Christopher Nolan whose next film - WWII battleship drama Dunkirk - will get an early 35mm/70mm release in cinemas that still project celluloid.
