There was a footage of Ma-Ti's death filmed for the cemetery scene but it did not make the final cut.
While filming the pawn shop scene, the police were actually called on the film crew.
Brad (the character of the film crew holding the boom who sleeps with Suzy) and Drew (the sound guy) are two of the directors of the film.
The original cut of the film had an extended version of the SPA (Super Powers Anonymous) meeting including two more characters with lines: Black Thunder and the Monocle Mistress.
