Those casts were wonderful, because they all realised that if one of them stood out of line, the whole thing would collapse, and they all played the game. Maggie Smith was very funny making Death on the Nile (1978), because everybody was slightly intimidated by Bette Davis (who was wonderful to work with). But Maggie and Bette had to play scenes together sitting in chairs facing each other, and Maggie kept having problems with her lines. She said she would look across and see Bette Davis talking and she kept thinking she was watching The Late Show on television, and she’d keep forgetting her lines. - Anthony Powell, costume designer for Death on the Nile.
