The now-legendary Steadicam trip through the nightclub kitchen was a happy accident. Scorsese had been denied permission to go through the front, and had to improvise an alternative.
BULLSHIT! This shot has been used as an example several times in different film courses. Not once have I ever heard a professor, film historian or book say this. I even took a Films of Scorsese course and they did not mention this. Scorsese is known for his used of long stedicam shots. He utilizes it in several of his films. Not the kind of thing that would be an accident. Especially for a director who puts so much thought into his work.
