Calling her involvement in a franchise like Marvel Studios' "Avengers" films "a childhood dream," Elizabeth Olsen opens up about "Captain America: Civil War" and what it means for her character, the Scarlet Witch.

"Being part of a Marvel movie makes me feel like I'm doing the most top secret thing in the world," the actress told Premiere.fr of her current position as one of earth's Mightiest Heroes. "I's ridiculous, 'cause it's a film, but it -- also, it's too bad when people want to spoil things about movies or paparazzi are on set and they're taking pictures of certain things. And everyone then gets to guess what it is that you're filming. And it ruins it for everyone. I was just so happy that in "Avengers [Age of Ultron"] we were able to keep a lot of things secret so there were surprises for the audience, which was great.

As for "Civil War," Olsen makes no bones about her enthusiasm for the film, which has been nicknamed "Avengers 2.5" due to its massive cast of heroes. "I think it's going to be the best one," she stated. "Daniel Brühl is an incredible actor and he's playing the main villain [Baron Zemo] in it. And he's incredible! It's a movie about people, as opposed to robots this time. So it's darker and it's allowed to be darker because it gets more in the mindset of humans rather than machines."
