Brad Pitt is somebody that gets no respect when it comes to being diverse. He is a great character actor. Twelve Monkeys, Fight Club, SNATCH, The Assasination of Jessie James by the Coward Robert Ford, Burn After Reading, Inglorious Basterds, The Curious Case of Benjamen Button. He has a lot of other good movies but those are some he had to step outside the box a good bit and showed his versatility as an actor.
Like Oldman, Pitt is a great character actor. The thing that sets him apart is that he has the looks and chops to pull off the traditional leading man role.
