BRAD PITT INSTEAD OF WILLIAM BALDWIN-
As I read that in the Trivia Section, I realized that it would've been a more interesting and enjoyable performance that of Brad Pitt because of his action-oriented appearance, it would've been more challenging against Russell's persona, unlike Baldwin, who looks like a preppy wimp, and when he saves Bull, it's definitely not credible, Brad Pitt's acting at that moment would've been like the actual redemption before his brother.
Now, if we consider that Brad's small role in Thelma & Louis was a trampoline on his career, maybe it was better this way --wouldn't like to see William Baldwin married to Angelina Jolie, you know what I mean?--. =D
