Ten Little Indians (1974)

Continuity mistake: The guests arrive by helicopter in Persepolis. They walk towards the hotel. The torrid Persian sun makes them cast a shado to their left. Elsa Martino greets them and escorts them for the last few meters in another shot, during which they cast shadows to the opposite direction. The two shots (and shadow directions) alternate.

Vera Clyde: You are a bastard, aren't you?
Hugh Lombard: Yes. But I'm not a killer.

Trivia: The voice of Mr. U.N. Owen on the tape is that of Orson Welles.
