The best moments can't be preconceived. I've spent a lot of time in editing rooms, and a scene can be technically perfect, with perfect delivery and facial expression and timing, and you remember all your lines, and it is dead.
When you see a person, do you just concentrate on their looks? It's just a first impression. Then there's someone who doesn't catch your eye immediately, but you talk to them and they become the most beautiful thing in the world. The greatest actors aren't what you would call beautiful sex symbols.
When I received my first paycheck from my now known day job, I spent it on a period Craftsman chair and a Frank Lloyd Wright-wannabe lamp. With my second paycheck, I bought a stereo.
That's the most important thing to me - that if I'm gonna spend however long it takes to make a movie, give up 14 hours a day for however many weeks or months, then it's very important for me to know that I'm working with people who I respect and enjoy and that we're going for something together.
