Young Frankenstein (1974)
1 visible crew/equipment mistake
Directed by: Mel Brooks
Starring: Peter Boyle, Gene Wilder, Teri Garr, Madeline Kahn, Marty Feldman
Continuity mistake: When Inga, Frederick, and Igor reach the secret library, Frederick reaches for the door knob to grasp it with his right hand, but the view from inside the room showing them entering has Frederick's right hand opening the door without using the knob.
Dr. Frederick Frankenstein: You know, I'm a rather brilliant surgeon. Perhaps I can help you with that hump.
Igor: What hump?
Trivia: When the Burgermeister says the village and townspeople were terrorized "five times before", it is a reference to incidents from five Frankenstein films: Frankenstein, Bride of Frankenstein, Son of Frankenstein, Ghost of Frankenstein, and House of Frankenstein.
