The sides are taking shape for Marvel Studios' upcoming "Captain America: Civil War." After some online chatter about her involvement in the project, actress Elizabeth Olsen has apparently confirmed that her "Avengers: Age of Ultron" character Scarlet Witch would appear in the upcoming superhero crossover film.

"I guess I'm allowed to talk about that now," the actress said at a promotional event with Joss Whedon according to a report on Comic Book Movie). Apparently, Olsen will re-don the red outfit of her superhero character two weeks from now as "Civil War" films in Atlanta.

That's an interesting turn for those comparing the new film to its event comic counterpart. While previously announced movie characters Captain America, Iron Man and Spider-Man all played a pivotal role in the Mark Millar/Steve McNiven series that gives the film its name, Scarlet Witch was well off the Marvel Universe map when the comics came out. Olsen's inclusion provides the biggest clue yet as to how Marvel Studios will approach the "hero versus hero" concept differently than Marvel Comics did.
