Young Frankenstein (1974)

Continuity mistake: In the scene where Inga, Fredrick and Igor throw the net over the monster, Inga sticks the syringe of the sedative in the monster's back but does not push down on the top, yet the monster still falls over. A few seconds later when she collapses on the monster, you can see all of the fluid inside spray out. (01:12:05)

Continuity mistake: When Igor is holding onto the cemetery gate, his hands swap between angles from holding two bars close to each other, to having an empty bar in between.

Sacha

Continuity mistake: The brain that Frankenstein draws on the blackboard in the first scene is different from the one behind him as he is seated and lecturing. Check the shading on the brain stem. (00:05:55 - 00:09:35)

Trivia: The Laboratory equipment is the same equipment used in the original Frankenstein.

Trivia: Another time you can see Gene Wilder laughing when he's not supposed to be is after he finds out the project failed (the quiet, dignity, and grace speech). He starts strangling the monster, and you can see that he is stifling laughter. Finally, he can't hold it in any longer and proceeds to partially hide his face behind the monster lying on the table in an attempt to cover up his smirks (but you can still see that he is laughing).

Trivia: The original cut of the film was three times the length of the final cut.

Dr. Frederick Frankenstein: You know, I'm a rather brilliant surgeon. Perhaps I can help you with that hump.
Igor: What hump?

Inga: Dr. Fronkensteen! Are you all right?
Fredrick Frankenstein: MY NAME...IS FRANKENSTEIN!

[A wolf is heard howling in the distance.]
Inga: Werewolf.
Frederick: Werewolf?
Igor: There.
Frederick: What?
Igor: [Points to moors] There wolf. [Points forward] There castle.
Frederick: Why are you talking like that?
Igor: I though you wanted to.
Frederick: No, I don't want to.
Igor: Suit yourself. I'm easy.

Question: What year is the film set?

Question: What is the melody that Frau Blucher plays to calm down the monster?

Question: Dr Frankenstein tells a student at a lecture he is giving that he is not interested in death but the preservation of life. If this is true then why would he continue in the footsteps of his grandfather?
