Creating the perfect villain takes a village. Not only is the villain's character dependent upon the actor, but the makeup crew has to work overtime to make their aura feel evil no matter how human they are. Whether the actor has to method act, don intense makeup, or rely on post-production CGI, there are a lot of components that go into making the perfect villain.
Calvin Candie - Leonardo DiCaprio
It's not often that DiCaprio plays a total villain, but he truly nailed his role as Calvin Candie in Django Unchained. This character is an immoral nightmare and, somehow, DiCaprio completely transformed himself into the role. For actors who are as well established as DiCaprio is, it's hard to watch a movie and not think about the actor themselves.
Even though Calvin Candie doesn't appear until we're midway into the film, he somehow demands the entire story around himself. DiCaprio crafted a memorable performance for someone who wasn't technically a "main character."
