Last night - I believe that it was on O'Reilly - a drama critic was talking about the negative effect that people like Clooney and Sean Penn are having on their own careers. He also mentioned Jane Fonda and Barbra Streisand. He could also have mentioned Ed Asner, whose career has been in the toilet for years for his pro-communist stances.
Penn apparently had a verbal agreement for something like $10 million to do a movie and after he went to Iraq the offer was withdrawn. He's now suing - and will probably lose.
Ah, so that's why he's popping up in all the shows lately. Well, at least two that I've seen recently.
