For me, filmmaking combines everything. That's the reason I've made cinema my life's work. In films, painting and literature, theatre and music come together. But a film is still a film.
I've learned, having been on a lot of sets, the good news is that by definition you are surrounded by experts. They get fired if they're not - unlike in the theatre!
Sometimes we go to a play and after the curtain has been up five minutes we have a sense of being able to settle back in the arms of the playwright. Instinctively we know that the playwright knows his business.
Unless comedy touches me as well as amuses me, it leaves me with a sense of having wasted my evening. I go to the theatre to be moved to laughter, not to be tickled or bustled into it.
