Trope Codifier for:
Stories and novels
- Market-Based Title: 4.50 from Paddington became What Mrs. McGillicuddy Saw! in the US.
Margaret Rutherford films
- Creator Backlash: Downplayed. Though Christie voiced dissatisfaction with the films due to their plot changes and Denser and Wackier tone, she did still dedicate the novel, The Mirror Crack'd From Side to Side to Rutherford "in admiration".
Miss Marple (BBC TV series starring Joan Hickson)
- The Danza: Hawes's first name is never mentioned in the book version of The Murder at the Vicarage, but in the BBC version, he's called Christopher, same as the actor who plays him.
- Fake American: Several but notably Claire Bloom as Marina Gregg in "The Mirror Crack'd From Side to Side" and Sue Lloyd with a hideous attempt at a Deep South American accent in "A Caribbean Mystery".
- The Other Darrin: Jason Rafiel is played by Frank Gatliff in Nemesis and Donald Pleasence in A Caribbean Mystery.
- You Look Familiar: Many years before starring in the BBC series, Joan Hickson played a housekeeper in one of the Margaret Rutherford films, "Murder, She Said".
- Appropriately, while criticizing the Rutherford films, Agatha Christie indicated Hickson by name as fitting her vision of what Miss Marple looked like.
