Hi Firestar, that sounds like a cool idea. Would your film be a documentary or fiction? I saw a documentary recently called Unlisted: A Story of Schizophrenia. It was really good. What I liked was the connection between the filmmaker and the topic. She made the movie but yet was a character in it too. It was about her and her father, who had schizophrenia. It was very touching, and I learned a lot about the mental health system. Here is more info on that film if you are interested:

Can you explain more about what you mean by a pro-psychiatry theme? Like, would you want a psychiatrist to be a main character and show him/her as a dedicated healer, etc.?
