This movie is so tragically bad; that you feel sorry for those involved. Adapted from a Kurt Vonnegut story, with some big name talents in the cast, the story is destroyed by a lame script, no slapstick or any comedy of any kind, and stars given nothing to work with. Jerry Lewis and Madeline Kahn play aliens who have a message for the world, and encounter evil everywhere--a depressing premise to start with. Versatile Pat Morita is wasted on a mean-spirited, stereotypical little loudmouth character that isn't the least bit funny--only irritating. Marty Feldman, Orson Welles, and Jim Backus have parts they probably hid from their resumes too. One recurring joke is that excrement is a new fuel source; this sad attempt at humor was as close to a laugh as you get. The film has only one worth while moment: a touching scene near the end where you actually get a chance to feel something for the two characters who have been mercilessly hurt throughout the movie. An unfunny comedy that will just leave you feeling empty.
