I worked for him in Hollywood playing on a sound track for "The Wild Rovers" an autoharp.
I went into the control room to hear the playback and encountered a contretemps between Blake Edwards and the composer for the score Jerry Goldsmith. It became quite heated and they swore that they'd never work together again. It was over a scene where the cowboys in the film are breaking in a horse. It was an education for me about how Hollywood invests in silly bickering and calls it artistic control.

It was a lose-lose situation. Doubt if many even heard of or saw the film. The horse may or may not have been broken but the film was.
