4. Michael C.Hall
The man who is known by people as the serial killer Dexter on the critically acclaimed TV show of the same name. I think this guy would make an incredibly good Ant-Man; he actually looks like Ant Man for a start, and he has the acting skills to pull it off. If you have seen him on Dexter you will know what I'm talking about. I know a lot of fans may think he would make a better villain for the Marvel Cinematic Universe, and if so comment on who he should play. However, I don't think just because he plays a serial killer on TV that he should automatically be cast as a villain all the time. I hate typecasting and I think a great actor like this should expand on the roles he could bring us, which makes him one of my choices for the shrinking superhero.
