As for ArthurHiller: Supposedly he was so disgusted with this movie that he had his name removed from the credits and replaced with, you guessed it, Alan Smithee.
The movie (directed by ArthurHiller, who, believe me, we'll be getting to) is shot as a mock documentary in which endless streams of clich d movie insiders, many of whom play themselves, turn to the camera and tell you what's been taking place.
