Box Office Bomb: The film only grossed $14.6 million on a $15 million budget and was one of the big flops of the 1985 Christmas season (possibly due to the Multiple Endings gimmick). However, it became a Cult Classic on video and cable (where all three endings appeared together).
Cool Guns: The gun that Professor Plum is given is the Harrington & Richardson Model 642, which is used by several people throughout the film, and the gun that the FBI use in this film is the Smith and Wesson Model 10.
