9. Tommy Lee Jones - Batman Forever (1995)
http://www.youtube.com/watch?v=xGZVwW5nyrE Granted, Batman Forever isn't quite as a awful as Batman & Robin, but let's face it: both of these movies are crimes against cinema in general, and that's partly due to all the downright terrible performances inherent to both of them. And Tommy Lee Jones, ever a figure of stoic brilliance and reliable authority, playing Two Face? Uh-uh. Tommy, you've done yourself a mighty diservice, my friend. I'm not sure what roped Tommy Lee Jones into this movie aside from the paycheck, but - watching this - you can't help escape the feeling that the man is wiping a soiled pair of undies on the front of his filmography. I mean, maybe some of the scenery chewing is appropriate, I guess, given that this is a comic book movie, but watching Jones do it feels like a violation. This is an uncomfortable viewing experience in every sense. Don't you even dare try to defend it!
