The unseen Star Wars archive footage used in Rogue One

“We went to Skywalker ranch, and there’s the archives there,” Edwards told RadioTimes.com.
“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.’”
Sensing an opportunity, Edwards got his hands on the film negatives, and realised he had the perfect chance for a subtle homage in his hands.

“We got the neg documents and found the clips from A New Hope that hadn’t been used,” he recalled.
