When this movie hit theaters, one famous actor was notably missing from the credits. He wasn't in a starring role or anything, he just wanted to be in the movie. In fact, at first, it was hard to recognize him at all in his role. For the record, the early scripts didn't really have his role, but when the director found out he wanted in on the movie, he (the director) hastily added a scene just so he (the famous actor) could be in it.
When this movie was in the planning stages, 2 actors worked on the script. They had the same agent. He recommended a third actor be cast for a role somewhere. When asked why, he admitted he represented all 3 of them, and it was good for him for the other guy to get a role also.
There was some disagreement over the budget. The studio came down with such a low budget for the movie that the director gave up on them and went to a different studio. They agreed, and the movie became a big hit, and rather famous.
I'm glad they were able to fix communications with the lighting director. He was given one set of directions, then later told the lighting was awful. Finally, one writer pointed out what they SHOULD have told him from the beginning but they had NOT. (They didn't want gloomy, dark lighting for the scenes, that would have hidden everything. They wanted the FEEL of gloomy, dark lighting, but scenes that were well lit any way.) The lighting director was then able to give them what they wanted. (Good thing he spoke up, the lighting director was getting ready to walk out.)
