Sean Penn In "Milk"

I've got my reservations about Gus Van Sant's upcoming biobic "Milk," starring Sean Penn as Harvey Milk, the first openly gay man to be electing to any political position of importance. Having seen the Oscar winning documentary "The Life and Times of Harvey Milk" makes me wonder why Penn was cast in a role that requires a fun loving individuel. I don't know, maybe it will be a good movie. In the mean time someone managed to tape a video of Sean Penn filming a scene live in San Francisco at City Hall. The audio isn't too clear, but now we have some clue as to how Penn will be acting in this movie.
