* ExecutiveMeddling: The first scene was added later at the insistence of Studio Executives who just didn't get the SupportingProtagonist story line. This may explain why it doesn't really fit with the way the movie ends.
* FakeAmerican: Kim Catrall (English-Canadian) as Gracie Law (American).
* WhatCouldHaveBeen: This was originally conceived as a Western with magical kung fu with Jack Burton character as a drifter. Then, it was retooled as a sequel to ''Film/TheAdventuresOfBuckarooBanzaiAcrossThe8thDimension''. That said, a sequel was considered but the film did not do well in theaters.
** However, on June 4, 2014, the comic series by BOOM! Studios started. It is written by Eric Powell and John Carpenter with artwork by Brian Churilla, and continues from where the film left off.
