The scene in which Deputy Reingold receives the Sheriff's nameplate in the mail and arranges it on Jake's desk was ad-libbed because the set designers neglected to put the nameplate on the Sheriff's desk before filming.
Hacksaw Jim Duggan filmed all of his scenes in one afternoon.
A cast was made of the director's head for the "Jimmy" kill scene but was never used.
The film was shot in less than two weeks.
The sheriff's office was a Storage R Us building.
