It's called "All the Great Operas in 10 Minutes". It is a hilarious short movie where the film maker uses Monty Python style paper cutouts to tell the story of the operas, giving a run down of the murders, suicides, rapes, incest, and walking talking statues from Hell (Don Giovanni). The film maker narrates the story lines in a somewhat bored voice that makes it even more funny.
ExGeeEye had it on his hard drive and graciously made a disc for me. The kids LOVED it, and Joseph is going to take it to school to see if his English teacher would like to show it in class.
