At the end of "Buckaroo Banzai" there is a credit which invites viewers to watch for a sequel entitled "Buckaroo Banzai Against the World Crime League." BB was directed by W.D. Richter in 1984. Richter set to work on a sequel to BB, presumably the one about the World Crime League. John Carpenter then stole Richter away from the idea and morphed his idea into the script for "Big Trouble in Little China." Go figure.
