I don't know if you have heard about this, but Russell Crowe will be portraying Bill Hicks for a new biopic. You can read a little more about it here
I don't know how I feel about how a film would turn out. It's kind of wierd to imagine a movie about a comedian instead of just a documentary. American: The Bill Hicks Story
was just so good that it seems hard to top that, even if it was a documentary.
