Ryan Reynolds
X-Men Origins: Wolverine (2009) & Deadpool films (2012 - )

Reynolds certainly hasn't been accused of vanity in his scarred portrayals of Wade Wilson/Deadpool in the Marvel movies. He plays a concept version of the character in X-Men Origins, but it's more silly than cool. It's the Deadpool movies you want to see. His scars are actually the result of oxygen deprivation, one of the many ways Wilson is tortured in the film.
