It's simple: You get a part. You play a part. You play it well. You do your work and you go home. And what is wonderful about movies is that once they're done they belong to the people. Once you make it it's what they see. That's where my head is at.
It's to paint directly on the canvas without any funny business as it were and I use almost pure turpentine to start with adding oil as I go along until the medium becomes pure oil. I use as little oil as I can possibly help and that's my method.
