Revealing mistake: When Captain Peacock goes behind the curtain to the hall way to Mr Rumbold's office, you can see that the sets are right next to each other and the other actors are waiting in there for the next scene.

1 mistake in Goodbye Mr. Grainger

Genres: Comedy
German Week - S3-E6
Miss Brahms: I think Mr. Rumbold should dress up as something.
Mrs. Slocombe: Yes. Wasn't Frankenstein a German?
Miss Brahms: That's right. With his nuts in his neck. [Makes twisting motions with her fingers near her neck.] Like that.
Mr. Rumbold: I wouldn't be able to take part, of course, in case I was summoned to a board meeting. But I see no reason why Captain Peacock shouldn't participate.
Captain Peacock: I can think of lots of reason why I shouldn't participate. Somebody has to have authority over the floor and these clothes that I wear symbolize that authority.
Mr Lucas: Why don't you dress up as Hitler?
Trivia: Frank Thornton, Mollie Sugden, John Inman, Wendy Richard and Nicholas Smith are the only actors to appear in all 69 episodes of the show.
Question: If Mrs. Slocombe had squatters in her new flat, why didn't she simply call the police and have them removed?
Answer: That wasn't possible in 1972. Until recently squatting was a civil offence in the UK, not a criminal one, and removing squatters was a complex and time consuming business.
