As we all know, by the time is film is shot till the final cut is locked in, there are a bunch for scenes that don't make to to screen. We will have to wait till the DVD release to actually see them but for now, here are some details about a few scenes that we know have been cut from Captain Marvel.
1) Ronan and Yon-Rogg
When Entertainment Weekly revealed the first look photos from the movie back in September, there was a BTS photo of Anna Boden directing Lee Pace (who plays Ronan) and Jude Law (Yong-Rogg) for a scene. That scene did not make it to the final cut, and in the movie we got, Yong-Rogg and Ronan never actually come face-to-face, instead talking to each other hologromams. From this 2nd photo released, which shows Starforce walking by Ronan, this scene takes place as they leave for their first mission in the start of the movie.
2) Yon-Rogg and Supreme Intelligence
In an interview with Collider, Jude Law confirmed that he had a scene with Supreme Intelligence that was cut from the movie. According to a redditor who worked on some of the VFX on the movie, that scene takes place right before Yon-Rogg is sent to find Carol and the Tesseract. Want to know who Yon-Rogg sees as Supreme Intelligence? [Spoiler (click to open)]It's himself.
3) Carol and Supreme Intelligence
According to the same redditor, almost a third of Carol's second interaction with Supreme Intelligence was cut. You might have noticed that the memorable (for me at least) line from the 2nd trailer which SI says to Carol "We made you one of us, so you could live longer, stronger, superior." wasn't actually in the movie. Apparently, the scene as shortened because TPTB felt that it dragged on a bit.
Additionally, directors Anna Boden and Ryan Fleck teased a "really kind of fascinating, bizarre, fun scene that didn't make it into the final film" in an interview.
