Ideological pressure is much more crippling than commercial pressure. Crippling to your own freedom of thinking and creating, crippling the final results.

Milos FormanPeople who make documentaries have to be faithful to the facts. But when you are making a drama, a fiction based on the life, all you have to be faithful to is the spirit of the facts, which I think I was in every case. As long as you don't violate their spirit, you can play with the facts.
