I'm pretty sure Elle MacPherson's character never found out his identity. As for the rest, I guess they could keep a secret. The plothole that always bugged me was Drew Barrymore and Debi Mazar finding out in Batman Forever, yet there were no consequences from this.
This website is pretty credible, having called a bunch of rumors in the past. I remember just recently they got their grubby paws on the Pirates of the Caribbean 3 script. So, I'll trust their info. Interesting choice. Definitely bucking the norm here. I was pulling for bats*t Crispin Glover, but oh well. In Nolan we trust.
I always thought that Ray Liotta would have been a good Joker if you were going for the crazy killer. Listen to his laugh in Field of Dreams when he talks about Ty Cobb; that is one crazy sounding laugh. Plus to give it a little extra realism all you would have to do is get him liquored up and then he could really pull it off
On second thoughts, Ledger wouldn't be bad for the role. If they made the Joker a transvestite it would work very well.
Heath Ledger is an embarrassment too all Australians. the guy couldn't act his way out of a paper bag.
Dude, you are so right. Liotta would make a kickass Joker. His laugh is absolutely perfect. Plus, he's got the crazy eyes too. Someone needs to call Nolan.
