My screenplays are very detailed. The reason they're detailed... you have to think on your feet. You have to be ready to change because there are no such things as ideal conditions.
Once the script is done, I put it aside for a month. I start thinking of all the films that have influenced me, which I have liked for different reasons, and not necessarily the look, but films that have moved me. Some very strange films came to mind.
I think it's really important not to be so judgmental and not to be so fearful. Try to have confidence in yourself. Don't depend so much on what others say about you or want you to be.
