Karyn Kupcinet's first and only movie appearance. She's the snooty girl in the red dress who infuriates Herbert by calling him "Herby". She was murdered two years later, a crime that remains unsolved.
During a 2008 interview, Mel Brooks noted that he wrote the original script for this movie, but since most of his work was excised from the final version asked that his name be removed from the credits. A handful of his comedy bits remain in the film, including a scene of Jerry Lewis dusting a trophy case and releasing the live butterflies within, and a scene in which Lewis goes through a car wash in a convertible with the top down.
During this production Jerry Lewis attached a small video camera to the side of his 35mm camera, in effect, pioneering the "video assist" system that is standard on just about every feature film today.
In the broken hat scene, Jerry Lewis can be seen and heard stifling giggles at the responses of famous actor George Raft (playing cameo role), while Lewis' back is to the camera.
