The first Star Wars: Anthology film, Rogue One, may or may not have already started shooting, despite the fact that, other than Felicity Jones (The Theory of Everything), we don't officially know the cast of the film. One person, however, who has been rumored to be attached to Rogue One is Diego Luna. Luna was reportedly cast in the film back in May however, because of an agreement between Disney and Paramount, Rogue One cannot be officially promoted until after the release of Mission Impossible: Rogue Nation, due to similarities in their titles.
Recently, the YouTube channel Bay Area HQ interviewed Luna about his new film Casanova and they snuck in a question about Rogue One. They asked if Luna would be playing Biggs Darklighter (originally played by Garrick Hagon in A New Hope), sighting physical similarities between Luna and Hagon (I don't see it). Luna danced around answering the question, simply saying, "I think I have a vague idea."
Check out the video for yourself below (the question is asked around 3:30),
It does seem from the video that Luna is probably in Rogue One, though I doubt it will be as Biggs.
