I'm not a player; I'm just a lovely guy, and I can show a girl a good time.
It's fun to play a dark character, but you go home at the end of the day not feeling very good about yourself. You go away feeling dirty. It seeps into the air.
You can have an amazing director and terrible script, and the film's not going to be great. But if you have the most incredible script and an okay director, you could still get a really good film.
