Trivia / And Then There Were None

• Post-Release Retitle: The novel was originally titled Ten Little Niggers in the UK. The initial US edition used the now-current And Then There Were None title, but subsequent paperback reprints from 1964 to 1986 used Ten Little Indians. The original US title was adopted for the UK reprints starting in 1985 and is now the official title. The translations that used the original UK title are slowly but surely switching to less offensive titles; the most recent one was the French version in 2020 and some languages have yet to change.
• Recycled Script: The 1965 and 1974 versions of the film basically recycle the 1945 film version's script, just changing names based on the actors playing them, and updating the locations from an island house to a resort in the Alps and an Iranian hotel. The 1974 version actually reuses some of the dialogue word-for-word from the 1965 version.

  • The name of the Touhou Project song "U.N. Owen Was Her", used as a bonus stage theme in multiple games, is a nod to the name given to the killer. The boss who originally used the song, Flandre Scarlet, also has a spellcard that references the book's title.
  • Square One TV: The Mathnet mystery "The Case of the Mystery Weekend" is a Whole-Plot Reference, with George and Pat dealing with a houseful of guests who start disappearing one by one (although they aren't killed, this being a kids' show). Even the motive is the same.
• Renamed to Avoid Association: The stage adaptation changed General MacArthur's name to General McKenzie, as by that time General Douglas MacArthur was playing a prominent role in the Pacific Theater of World War II. Early film adaptations changed it to Mandrake.
• What Could Have Been: Vera's original motivation was poisoning her husband's lover. That was deemed much too bland and Cyril was born. The movies use it anyway.
• You Look Familiar: Herbert Lom was cast in the 1974 version as Dr. Edward Armstrong. He returned in the 1989 remake to play General Branco Romensky. Ironically, he's billed higher in the 1989 version than he is in the 1974 version, despite the general being a smaller role (fourth billing in '98 vs. sixth in '74.
