After Director of Photography John Alton agreed to shoot this movie, he asked Producer Benedict Bogeaus how much he had budgeted for rigging - the system of overhead pipes, brackets, ropes, and cables that suspend lights over a film set. Bogeaus told him four thousand dollars. "Give me two thousand dollars above my salary and I won't use any rigging", said Alton. He did it by using almost no overhead lighting at all, contributing to the film's rich visual atmosphere.
Shot in nine days.
