Secrecy is Marvel Studios' middle name, and Age of Ultron's Elizabeth Olsen is getting the ultimate crash course in the art of saying nothing.

The 25-year-old actress is portraying Scarlet Witch in the Phase 2 capstone project, and Olsen's first Marvel film happens to be one with the most media due to the success of 2012's The Avengers.

"Any time they give us a call sheet or any time there's a new draft, they have to shred our old papers," Olsen told Flaunt of the film's strict adherence to Marvel's cone of silence. "I don't think I'm allowed to say anything! And I'm too terrified. I really just feel like I'm doing something that's top secret and somehow has a lot more importance than anything else I've been around, so that alone is hilarious."

However, Olsen did comment on what is feels like to spend her working hours playing a powerful superhero.

"I do think, doing things like The Avengers, I've noticed I've felt really confident recently," Olsen explained. "And I think it's because I get to be very confident physically all day. I get to be a kind of grounded badass. And if that's rubbing off on me, then that's fun."

Fans will have to wait until Age of Ultron's 2015 release to really find out what Joss Whedon's cast has been up to.
