I don't blame him. Those are some big shoes to fill, and the fans are the ones who will get the most upset with this. I've never really seen Evans in a real serious role, but I can tell you that I thought he did a pretty good job with Johnny Storm in the Fantastic Four films, even if the films were less than fantastic. (see what I did there?) He personally wasn't my first choice for the role, but I think he'll do fine. As long as he just plays the role to the best of his ability, and he ignores the worry-warts on the internet, I'm sure he'll do a great job as Captain America. Heck, he may even redefine the role as Heath Ledger did with the Joker. Heath spent a lot of time on teen-romance-comedy type films, and after breaking through in Brokeback Mountain, he is now known to many people for his work in that film as well as The Dark Knight. I'm not saying that Chris will for sure have that effect after playing Cap, but it's a possibility.
I'm a little scared, to be honest. I'd be lying if I said anything else, and I have no problem being honest about that. It's intimidating. It's a big responsibility and you want to do your best work... It was a challenging process for me, trying to decide whether or not to do it... the script is great and it's going to be a fun character to play... He's an incredibly noble, honest, selfless man, and those are qualities that I think people can aspire to and look up to.
Chris is now becoming a comic book film icon as in addition to Human Torch, Captain America, and as Jensen of the Losers, he'll be appearing in Scott Pilgrim this summer as Lucas Lee. He will officially have more comic related roles than Ryan Reynolds when Captain America comes out. Captain America: The First Avenger will hit theaters next year, so you've got some time before the film comes out.
What do you guys think about Evans as Cap? Should he be scared to take on the role?
