I don't want to make a film that offends people, but the whole world is so politically correct - I'm not going to not do something because it may be politically incorrect. At some point, the metaphors and allegories break down. They disappear, and you just have science fiction.
If you're a theater director, you're not going to be prepared for the technical side. And if you're a technical director, you're not going to be prepared for the acting side. The only thing you can do is go through the meat grinder of your first film.
I love the idea of people being themselves in films.
