Perhaps one of the toughest jobs for an actor is to play a real life person in a biopic. When an actor is playing a fictional character, they usually have creative license to invent whatever mannerisms and incidental character traits they see fit. But, when an actor is depicting a real person, whether living or dead, they have to try and be true to who that person was, which is certainly more challenging. And then there's the aesthetic side of things. Obviously, makeup and wardrobe is key here, but some actors look much more like the real life person they're playing than others. Take a look at these 28 actors versus the real life people they played in biopics.
