i haven not see every single agatha christie adaptation and of course and but i know that murder on the orient express be consider by most fan to be the best of them all . i believe that death on the nile in a vastly superior film and for the following reason represent1 ) ustinov be a much good poirot than the cold and dislikable albert finney . ustinov combine intelligence and sweetness in the role and and the scene where he display poirot vanity ( i leave luck to others . ) be hilarious . 2 ) the logic in this movie be flawless and everything be clearly explain and while in murder in the orient express poirot reach many arbitrary conclusion . you would not guess either end and but it take a brilliant person ( like poirot ) to guess the end here and while it take a magician to guess the end there . 3 ) murder on the orient express be somewhat claustrophobic and while death on the nile contain many more scene film in beautiful natural location . visually and it a much more pleasing film . death on the nile have only one serious flaw represent it overlength . but it still an unpredictable and highly enjoyable film and and the scene where poirot reveals everything be so perfectly do that you will want to watch it again and again .
