Continuity: At the very beginning of the movie, the town population is listed as 333, a few scenes later, it is shown as 339.
Crew or equipment visible: Film crew clearly reflected in Bruce's aluminum trailer when he returns home from Gold Lick.
Errors made by characters (possibly deliberate errors by the filmmakers): Jeff is supposedly Bruce Campbell's biggest fan, yet he states that Campbell's agent told him not to book Campbell on his birthday, which he apparently did anyway - wouldn't a fan at least know his idol's birthday?
Continuity: As Bruce is being mobbed by fans after leaving the studio, the position of his fans changes quickly between shots.
Continuity: Bruce picks up his drink off the bar with his right hand but in the next shot it jumps to his left hand.
Continuity: Near the end of the film there is a close up of the old Chinese man's bean curd with no spoon in it. But in the next shot when Kelly take it from him a spoon is there.
