I worked on a film and they required me to sign a clause that stipulated I could not say anything negative about them – ever. This became weirder by the time I grasped they were absolute assholes. I needed the money, I needed the job but I also need my dignity and it took the fall.
Two lawyers later, I decided I won’t do that again and addressed it in subsequent jobs. If you have a clause like that get someone else, I’m the wrong guy and the weirdest part is it’s not a problem. The issue has absolutely nothing to do with whether someone is the right composer for the movie it has everything to do with out of control power and insecurity.
