The Sam to Jensen Ackles' Dean on the hit show Supernatural. A lot of great actors start in television, and if you have seen Supernatural you will know this guy is a pretty damn good actor. He has only been nominated for Teen Choice Awards, so we need to make sure he is known better than that. He has the look for Ant-Man, and casting him as a superhero may give him the boost he needs to go onto bigger things. Besides, it's a lot better than casting Taylor Lautner as a superhero, am I right? Give this guy a chance; no one really knew who Chris Hemsworth was before he was Thor, and look at him now, seen by audiences as an incredible actor and not being defined by his brother Liam. I wouldn't be disappointed if he landed the role of Ant-Man.
