High Anxiety (1977) - 6 mistakes

Continuity: There is a scene at an airport where Mel Brooks is approached by a man claiming to be a FBI agent or something like that. In the next shot inside the bathroom you can see the boom microphone from the top of the screen.

Continuity: Madeline Kahn and Mel Brooks are in a hotel room in San Francisco. She is smoking a cigarette which grows shorter as the scene progresses. After cutting away and then back to her, the cigarette is long again.

Factual error: When Dr. Richard Thorndike sees his former professor Dr Lilloman right after first arriving at the institute, Dr Lilloman quizzes him by asking, "a patient comes into your office suffering from Belldon's Hysteria, and he has a seizure right in your office, what do you give him?". Dr Thorndike responds "2 cc's of aqueous Thorazine coupled with Somadiozine". There is no such thing as Belldon's Hysteria, and there is such a thing as Thorazine but it is used for bipolar depression but there is no AQUEOUS Thorazine. There is also no such drug as Somadiozine.

Other: When Mel Brooks is singing the song "High Anxiety" to a bunch of people in the dining room, near the end of the song he sings about two words and his mouth is clearly not moving.

Revealing: Mel jumps over a step that he senses to be weak. The step he actually jumps onto (and collapses) has been pre-cut in a zig-zag pattern.

Continuity: When the doctors are trying to save the patient from being killed, Mel Brooks runs up a long flight of steps in the clock tower. But, during his climb, he saw that there was a step which was cracked, so he avoided it by jumping over it. When he landed on the step above it, he fell through. While he was dangling from a step, you can see that the one that he jumped over is no longer cracked.
