 The film was shot as if it had been made in 1945. Only studio back  lots, sets and local Los Angeles locations were used. No radio  microphones were used, the film was lit with only incandescent  lights and period lenses were used on the cameras. The actors were  directed to perform in a presentational, stage style. The only  allowance was the inclusion of nudity, violence and cursing which  would have been forbidden by the Production Code.
