Rogue One has a number of tricks up its sleeve when it comes to paying homage to the original Star Wars films that follow it in the timeline, but this one you might have missed.

*Very mild spoilers if you’ve yet to see the film*

It goes to great lengths to achieve visuals in keeping with the 1977 movie, not just through costume, lighting etc but by using actual footage from the original shoot.

“We went to Skywalker ranch, and there’s the archives there,” Edwards told the Radio Times.

“And as we’re walking around, and doing all the cool things and looking at the Millennium Falcon and trying on Han Solo’s jacket and things like that, in the back at the bottom was all these cans of film. And we said ‘what are they?’ and they said ‘Oh, it’s Star Wars.’

“And you go… ‘has someone gone through all this? And it’s like ‘not really, they’re not fully like digitised at all.’”

Every lightsaber in Star Wars history (films) Show all 12 1 /12 Every lightsaber in Star Wars history (films) Every lightsaber in Star Wars history (films) General Grievous The general played a big part in the Clone Wars, collecting dead Jedi's lightsaber's along the way and using them to do a crazy spin-attack. Unfortunately, they all get cut off by Obi-Wan just a little too quickly. Every lightsaber in Star Wars history (films) Qui-Gon Jinn Obi-Wan's master really didn't have too much time on screen, but his battles with Darth Maul will go down as some of the best in Star Wars history. Every lightsaber in Star Wars history (films) The Emperor It was a little weird seeing The Emperor, at this stage Palpatine, getting out a lightsaber and battling Jedi. Much better when just using Force lightning! Every lightsaber in Star Wars history (films) Anakin Skywalker/Luke Skywalker/Finn Now, this one really does have some history, travelling down the generations of Skywalkers, and briefly using by Finn in The Force Awakens. Of course, **Spoiler** someone else also uses the saber after it calls to them, could they be a Skywalker to? Every lightsaber in Star Wars history (films) Darth Vader The first red-lightsaber we ever saw on screen: the definition of evil and an iconic weapon. Every lightsaber in Star Wars history (films) Yoda Again, a little odd seeing a character from the Original Trilogy using a saber, especially when he was jumping around after putting down his walking cane. Ah well, doesn't stop Yoda being a brilliant mentor to Luke. Every lightsaber in Star Wars history (films) Mace Windu Samuel L. Jackson managed to someone get George Lucas to give him a purple lightsaber, just to stand out from the rest of the crowd. That's one bad*ss motherlightsaber. Every lightsaber in Star Wars history (films) Obi-Wan Sure, Obi-Wan managed to lose his saber on countless occasions throughout the prequels, but at least he had it in A New Hope when going against Vader. Because that went well... Every lightsaber in Star Wars history (films) Darth Maul Maul's double ended lightsaber may have been the best thing about Phantom Menace. Scratch that, he was the best thing about that film! The last battle between Maul, Jinn and Obi-Wan was phenomenal, just a shame Maul didn't last until the next film (of course, he came back in The Clone Wars TV show, but that will take a little too long to explain here) Every lightsaber in Star Wars history (films) Kylo Ren At first, the cross lightsaber was mocked by the Internet for being impractical. Yet, when seen in the movie, it's ferocious, spitting out light due to be unstable, much like it's master. Every lightsaber in Star Wars history (films) Count Dooku Now, Dooku's character wasn't in the films for very long, feeling hugely underutilised, especially considering it was the great Christopher Lee, who took on the role as he was a trained fencer. It was still hugely impressive for an 80-year-old to be the best sword fighter in the galaxy. Every lightsaber in Star Wars history (films) Luke Skywalker Luke's second saber, after the one he inherited from his father, was originally going to be blue as well. Yet, due to not standing out against the Tatooine landscape, it was changed to green - which is why in early posters his saber is blue.

The cans turned out to be a treasure trove, containing unused shots from the infamous Rebel squadron call sign scene ahead of the Death Star assault.

“We got the neg documents and found the clips from A New Hope that hadn’t been used,” Edwards explained. “And there’s pilot photography and lines that were never featured in A New Hope."

The visual effects team were able to use these clips in the film’s very own X-Wing attack scene near its climax.

“Through the magic of ILM [special effect studio Industrial Light and Magic] they cut round them and manipulated them and stuck them into our cockpits,” Edwards added.

“It’s the sort of thing you think, ‘how many people will notice?’ Do you know what I mean? It’s like, is this a lot of effort for very little reward?”

“At the world premiere in LA, there was this massive cheer at a particular point in the film [there was at the screening I went to also]. “It was the only time during the premiere where I actually punched the air.”
