Impossible to keep serious...
I have seen this movie for the first time tonight. Impossible not to laugh at the many clues to Young Frankenstein; and to the Rocky Horror Picture Show, too!
Here's some:
The internal architecture with the curved stairway, and the guests at the ceremony, form RHPS; The servant, a mix of Igor and Riff Raff; the rigid, broom-in-the arse acting of Lugosi and Karloff, from YF; The police squad, and the train and bus journey, from YF;The electric panel, from both; I also recognized Frau Blucher!
I definitely should have seen this movie first.
