In an interview with Empire Magazine, Chris Evans said that he was initially unsure about taking on the role of Captain America:
"It was a couple of weeks weighing all the options. There was certainly a period where I was shying away from the movie. It's intimidating. It's pretty daunting. There's certainly a life-changing role there and that was part of the process."
"Did I want to take this on? I like supporting roles, I like the way my life is now and I have the best of both worlds. This would potentially change that. But you know what? This could be a good thing."
Evans also went on to reveal that he's not too familiar with the character and so has been preparing for the role by catching up on his comic book reading, "I have to start reading some comic books in order to get an idea of who this guy is and where he came from, before I can start building the character."
The First Avenger: Captain America is set to be released on July 22nd, 2011.
