Trivia: The Lady from Shanghai
- Copiously Credited Creator: Produced, directed, co-written by, and starring Welles.
- Dyeing for Your Art: Hayworth, famous for her luxuriant red hair, got a short haircut and went platinum blonde for this movie.
- Executive Meddling: As was often the case with Welles' work. The original cut ran around 155 minutes (including a much-extended funhouse climax) and had a much different musical score (the Hall of Mirrors segment was intended to play entirely without music). Studio execs ended up cutting almost half the runtime and commissioning a jazzy score designed to underline the action.
- Fake Irish: Orson Welles
- Germans Love David Hasselhoff: Although the initial reaction to the movie in the US was lukewarm, European critics loved it. Nowadays, though, it is almost universally considered to be a classic.
