Toronto--In a year filled with a new "Star Wars" film and the debut of Ben Affleck as Batman, all eyes are still on "Avengers: Age of Ultron," the sequel to the third highest-grossing film of all time that's set to assemble in theaters in the summer of 2015. In addition to the rest of the returning super team, a few new recruits will be added: Quicksilver and the Scarlet Witch--the latter of which is rumored to be played by Elizabeth Olsen.

MTV News' Josh Horowitz got to grill Olsen about her possible secret identity while the actress was promoting her new film "Kill Your Darlings" at the Toronto International Film Festival. As with any Marvel movie, the actress could not divulge just how deep her ties run to the in-development sequel.

"I've been rumored about lots of things," she said. The actress, most known for indie dramas like "Martha Marcy May Marlene" and "Liberal Arts," did reveal that the genre does hold interest for her, as she believes it holds interest for every actor.

"I grew up loving comic books and sci-fi," explained Olsen. "I think that's how everyone's first love for movies [develops], [by enjoying that] kind of entertainment as kids. I think those movies are great. I'd love to do something like that."

The Marvel films have attracted similarly dramatic minded actors in the past. Olsen would fit right in with the current Avengers, which include the Academy Award nominated Mark Ruffalo and Scarlett Johansson, a former Woody Allen ingenue.

Olsen did resist the urge to further rumors of her involvement and kept quiet about whether or not she's been doing her homework on the Scarlet Witch. "I never read [her appearances]. I just know comic books from my brother. No, that's not a character that I'm really well aware of until, you know, the internet."

If you're still scratching your head about the character Olsen may be portraying in "Avengers: Age of Ultron," here are five essential facts about the Scarlet Witch.

"Kill Your Darlings" opens in theaters on October 16th.
