I'm not sure if anyone has been cast, but Brad Pitt is listed on the IMDB as being in talks to play the part. Honestly, Pitt seems like he would be a good choice for the role. His Tyler Durder is one of the greatest characters in modern film, IMHO. The rest of the cast is still up in the air.
His name is Tyler Durden.

I like to mock Brad Pitt as much as the next guy, but I have to admit, he isn't scared to look and act nasty in pursuit of acting excellence.
His "12 Monkeys" character was electrifying. Tyler Durden was magnificent.
He may very well be the John Lithgow of the younger set - such a chameleon, you forget you're watching Brad Pitt.
