The title of a 1987 movie that starred Bill Cosby as a CIA agent who saves the world from an evil vegetarian. (Leonard Parts 1-5 were locked up in the interest of national security.)

Cosby wrote and produced the movie, but was so disappointed at how badly it turned out that he went on TV and urged people not to waste their time and money on seeing it.

Now that’s a bad movie.
