For most actors, one would think the idea of tackling the role of a famed superhero like Captain America would be the opportunity of a lifetime. An "easy yes," as they say in the biz. However, for the newly anointed star-spangled-superhero Chris Evans, the decision to take on the iconic character was a lot more complicated than simply saying yes or no to the part.

"No, it wasn't an easy yes," Evans told MTV News when he stopped by the MTV News/ MySpace Comic-Con livestream. "I get nervous. I get nervous in things like this [referring to interviews and public appearances]. Captain America means a lot of this."

Evans admitted that the decision was a particularly tough one because he was in a really happy place in his life and his career, and wasn't sure if he was ready to be catapulted into such a specific, fans-obsessing-over-every-detail-type spotlight. "[Playing] Captain America just changes things, and there's really no off switch once you walk down that road."

Evans went on to say, however, that his reservations don't in any way damper his excitement for making the film.

"There's nothing wrong with the project," Evans explained. "I love the people involved, the character, the script, Hugo [Weaving]. There was nothing wrong there, it was just about the lifestyle change and whether or not I was willing to do it."

Evans acknowledges the work he has cut out for him, but he's trying to get to a place where he can just enjoy himself.

"There's no turning back now," he said. "I'm just trying to make all the negatives positives and just enjoy the ride."
