Photos of Actors Who Completely Transformed for a Biopic Role
Biographical films require actors to perform something rather unusual. Rather than creating a character from scratch, actors have to become someone else—someone whose voice, look, and mannerisms are already familiar to the world.
For some actors, this means that the challenge brings out incredible changes in their appearance and mannerisms. With hard work and dedication, they remake themselves to become someone else in a rather uncanny manner.

Eddie Redmayne as Stephen Hawking

In The Theory of Everything, Eddie Redmayne portrayed physicist Stephen Hawking over several decades of his life. The role required depicting the gradual progression of a neurological condition.

Austin Butler as Elvis Presley

When Acting Becomes Transformation

Biographical performances have been known to take actors to extremes beyond ordinary roles. The physical changes, voice overs, and research all come together to bring history to life in front of the audience.
The best performances are those that go beyond mere imitation to reveal the person behind the public figure. These changes serve to remind people how powerful storytelling can be when it meets with history.
A well-thought-out performance can be like a bridge between two worlds, giving people a chance to look at history in a different way.
