This is a documentary of the legendary 'lost' Jerry Lewis 1972 film, "The Day The Clown Cried". Jerry plays political prisoner Helmet the clown in a Nazi concentration camp where he is eventually given the task of leading a group of kids to gleefully walk into the gas chamber.
The early section has a lot of present day celebrities and commentators talking about the rumors of the legend. Harry Shearer is one of the few who claims to have seen a copy. Apparently, some film cans of the working copy were secreted away from the bankrupt production house on their way to the trash. This does show some clips of the unfinished film. Some scenes are enlightening on the tone of the film, but it is tough to know if it's actually good or not. I don't think that this can be a comedy and that's the central question.
The big difficulty for the production is a lying producer who didn't get the rights to the story. In one section, Jerry confesses that the film is not good. He does pull it back by saying that it's almost wonderful which is not good enough. It's a dodge. I find myself wanting to call Jerry out on some of his comments. I'm not sure that he has a grasp on what the film needs to achieve. This is also well before Life is Beautiful and I've always felt that Life's broad comedy never worked due to the subject matter. It would have been great to have Jerry finish the movie. It would have been controversial and maybe set him on a different path.
