Most of the problems I hear about are not about the reality of it. It has to do with ego. If one is able to explain to another person why something should be done in a certain way, there is only one way to understand. It leads to the absence of dialogue. My perception is that once someone wants to produce the movie that you desire, they are not the enemy, they are friends.
Friends sometimes disagree but it's good to take their advice.
Of course, I think that one day I'm going to get hurt because I've been having such a friendly relationship with people who helped me do my movies. I hope not, but I'm a realist. This is a very untypical experience in Los Angeles, and I reiterate that it really creates a problem for me in Europe where Hollywood is seen like the devil on earth. I have lunch with the devil and I am not the food.
