Poirot mentions a Moulage Test in the denouement. The test he describes is a dermal nitrate test, which was first used in 1933. Moulage is the theatrical technique of using prosthetic make-up to add fake injuries to someone. This was a key element of the first murder in the film.
According to producer Richard Goodwin, Bette Davis brought her own make-up, mirrors, and lights to Egypt.
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.
Angela Lansbury had never seen the finished film until she attended a 40th Anniversary screening on November 9, 2018.
