Death on the Nile (1978)

Continuity mistake: In the scene where Bette Davis has lost her shawl there is a shot of her and Maggie Smith from far away. They talk about the time and in the background Angela Lansbury is drinking. She puts down her glass and leans her head on her hand. Then the shot changes to a close-up of Bette Davis and Maggie Smith and you can see Angela Lansbury in the background, with the glass in her hand, just about to take a drink. (00:55:05)

Mrs. Van Schuyler: You need a nice cool holiday, I was thinking of a trip along the Gobi Desert.

Trivia: The cast were told they could not have their own dressing rooms so Angela Lansbury, Maggie Smith and Bette Davis all shared a room.
