I'm a big collector of vinyl - I have a record room in my house - and I've always had a huge soundtrack album collection. So what I do as I'm writing a movie is go through all those songs trying to find good songs for fights or good pieces of music to layer into the film.
Being a funny person does an awful lot of things to you. You feel that you mustn't get serious with people. They don't expect it from you and they don't want to see it. You're not entitled to be serious you're a clown.
