Shooting began in Stockholm, but producer Nat Wachsberger not only ran out of money to complete the film, but failed to pay Joan O'Brien for the rights to the story. Jerry Lewis was forced to finish the picture with his own money. The film has been tied up in litigation ever since, and all of the parties involved have never been able to reach an agreeable settlement. Lewis refuses to discuss the making of this film in any form.
Jerry Lewis lost close to 40 pounds to play the role.
One of the most talked about, yet little seen, films in history, only a select few have ever seen the film. Among them, actor Harry Shearer who told Spy Magazine that the film was "perfect" in its awfulness.
