Did a couple of cute movies when he was younger. Haven't been impressed with any of his more recent stuff. "Born on the Fourth of July" was probably his best work...lately they've mostly been action, "look at me I'm such a hero" movies.
As far as this thing with Katie Holmes...he's a fool (there's no fool like an old fool) and she's a bigger one. His track record isn't too hot...what makes her think she'll do any better? I'd be in a tizz if I was her mother! The fact that he was Tom Cruise wouldn't impress me.
As far as the Scientology stuff...I can't stand prolestylizing in any form, of any religion, including my own. IMHO, you are free to worship whomever or whatever you choose...don't jam it down my throat. If I am interested in hearing about your beliefs, I'll ask you. If I were at a meeting with TC and he started that crap, I'd leave too. I think rkrivas hit the naill on the head...his last publicist kept him in line some. Now that his sister's his publicist, and she's a Scientologist too, all bets are off.
