5. Matt Boomer
In recent years Matt Boomer has proven to the world that he's a really good actor capable of not only being really good looking, but also being able to make really good performances both in comedy and drama (which can explain why he was in the running for Superman in Superman Returns). Considering that his career is growing stronger each day it wouldn't be a surprise if someone wanted Boomer as a superhero. He does have the looks to play a young Stephen Strange, however I'm not really sure if he can deliver as the powerful magician we all know in the comics. Nevertheless he's still a good actor, it would be really good to see him on the big screen starring in a good role and not just in the god-awful adaptation of a terrible novel as some people suggest.
