One of the most epic scenes in Rogue One: A Star Wars Story is the final scene with Darth Vader being a badass and killing everyone in his path. It turns out that the awesome scene was a last-minute addition that was shot three months before the film was released in theaters.
Speaking to Fandango, director Gareth Edwards revealed how the Darth Vader idea was pitched and how he was originally never going to board the Rebel ship:
"He arrives and obliterates the Calamari ship, and then the blockade runner gets out just in time and he pursues the blockade runner. And then Jabez was like, 'I think we need to get Darth on that ship,' and I thought, yeah, that's a brilliant idea and would love to do it, but there's no way they're going to let us do it. It's a big number and we had, what, like 3 or 4 months before release. Kathy [Kennedy] came in and Jabez thought, f*ck it, and pitched her this idea, and she loved it. Suddenly within a week or two we were at Pinewood shooting that scene.
Because it was my last chance to do Star Wars, and because you know it's the end, we really were very careful with it. We storyboarded absolutely everything and tried to have no regrets.
It just felt right; it felt like the right thing to do. It really is just the greatest hits of Darth; that corridor. And we really didn't want to do anything you haven't seen him do so it didn't throw people off. We kept it to what had been established."
Edwards went to say that the stunt team "came up with a whole shopping list of ideas. 70% we used, and maybe 30% felt a little too extreme. They were things you hadn't seen him do before."
I'm glad that they were able to shoot this amazing scene that wasn't planned in the beginning. It's not like the scene looked forced into the story; it actually connects to A New Hope well. The film would probably be dull without it.
