Seriously, I hate when people say he is a terrible actor. I actually think he is one of the best. Just watch this movie and I you will realize just how amazing his performance is. Whether or not he is crazy is a different question...
shareLeaving Las Vegas is one of my all time favorites and so is Cage as an actor. So many bad mouth him saying he has no depth or whatever but to me he is so convincing in his movies it's hard to believe it isn't him in real life too. He might be a little 'off' in the marbles game in real life but so are many highly artistic people so it wouldn't surprise me to learn that it is true about him.
