According to producer Richard Goodwin, Bette Davis brought her own make-up, mirrors, and lights to Egypt, just in case they did not have any there.
Bette Davis, Dame Maggie Smith, and Dame Angela Lansbury all shared a small steamboat cabin as a dressing room. While one actress dressed in the center of the cabin, the two others would lie on one of the beds on the left or right side.
Dame Angela Lansbury had never seen the finished film version of Death on the Nile (1978) until she attended a 40th Anniversary screening on November 9, 2018.
