12 Side-By-Side Photos Of Actors Who Played Other Actors, And I'm Really Impressed By How Much They Look Alike

Biopics are an endless genre in Hollywood. It seems just about every week there's a new, usually inspiring film released that's about a real person...or inspired by a real person. Everyone from scientists to athletes to singers to, honestly, notable figures in any profession can be fodder for a film.

Over the weekend, a new biopic premiered: Oppenheimer, starring Cillian Murphy as physicist J. Robert Oppenheimer. But there was a bigger film that was also released this weekend: Barbie, starring Margot Robbie. It beat Oppenheimer at the box office.
