"It's a big commitment," the actor told
Total Film in a recent interview.
"At one point it was nine pictures. We've got it down to six but still, that's making a decision for a big portion of your life. I love acting but there are other things I want to do. I want to write and direct. If the movies do well and they want to exercise all six films, I could be doing this until I'm 40."
"That's a crazy thing to try and process."
The actor then went on to talk about the pressures and responsibilities of bringing such an iconic and well loved character to life on the big screen:
"It's important, you know at the end of the day we are doing this for the fans. And if they're not happy, we've missed the mark. You go in and do as much research as you can from the comic books, but you're also trying to make something your own. This is an origin story."
"I think a lot of the comic books deal with after he's become Captain America, so to some degree we had to take some liberties. But you want to make sure you've done your homework."
Evans also told the magazine, which is on sale now, that he is keen for the character to remain human, and not disappear beneath the iconic status:
"You want the character to be the icon, but if you reduce him to a red, white and blue outfit it makes him shallow."
"It wasn't until we got our hands dirty with the script and had a good couple of scenes in the can, that I thought, 'Man, I think I'm actually getting this guy.' I feel like the character now, much more than a shield or a mask."
Captain America: The First Avenger is set to be released on July 22, later this year!
