Evans, 33, said he was nervous when he first landed the role because he was worried comic book fans wouldn't accept him, reported Contactmusic.
Replying to a question if it's easy to slip back into character, the "Fantastic Four" actor said, "Absolutely. When you first take on the role, it's intimidating, and you're scared the fans may not accept you.
"Now, I feel incredibly comfortable with it, and that's when you start trying to challenge the character and forge new territory," Evans added.
The actor who began his career on the television series Opposite Sex (2000) had played the titular role again in 2015 film "Avengers: Age of Ultron".
Evans will reprise the role for the 2016 sequel.
