After Rogue One was released everyone pointed out the scenes in the first two teaser trailers (and Celebration behind the scenes video) that didn’t end up in the final movie. Wild conspiracy theories and bogus clickbait flooded the internet of some secret alternate version of Rogue One, and now Gareth Edwards explained what happened with those scenes.
It was in Empire’s podcast, which Comic Book Movie has a transcription of, and he said this about those alternate Scarif scenes:
“There was a bit of a process to refining the third act in terms of the specific shots and moments, and so certain things just fell away. But then what happens is marketing love those shots, and go, ‘oh, we’ve got to use that.’ And you say, ‘well, it’s not in the movie’. And they say, ‘it’s okay, it’s what marketing does, we just use the best of whatever you’ve done.’ And so there’s lots of little things, but towards the end you go, ‘I know that’s not in the film, but the spirit of it’s in the film’.”
He also revealed that the very first draft of the script did have an opening crawl on it, but as everyone knows that was removed. The scenes with Krennic and Galen at the beginning are basically the movie’s opening crawl now.
