Out of the actors, probably Ryan Reynolds. Although he can do some serious work, he never fails to make me laugh. I love his Maximum Effort channel too. He also is the spokesperson for Mint mobile, and although I don't have it it seems pretty good. Their prices are so low that they have to be losing money, so I suspect Ryan uses his own money to help out.
Out of the heroes, I've got to say Wolverine. I love, love complex antiheroes like him. Yes, Deadpool is one too, but Wolverine does it in a more serious way that Deadpool seems like a satire of. Overall, I like them both. Deadpool and Wolverine are like Yin and Yang to me. I'm excited to see more of their dynamic in the new movie.
