Trivia

According to producer Richard Goodwin, Bette Davis brought her own make-up, mirrors, and lights to Egypt.

During World War II, Major David Niven's batman (personal attendant) was Private Peter Ustinov.

Location shooting in Egypt consisted of four weeks on the riverboat "S.S. Karnak" and three weeks filming in places such as Luxor, Cairo, Aswan, and Abu Simbel.

This was the first of Sir Peter Ustinov's six performances as Hercule Poirot.

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.
