Not as good as Death on the Nile--Peter Ustinov's first appearance as Hercule Poirot--but another stellar cast with mostly very good performances, witty lines, and high production values make this worth your while if you are an Agatha Christie fan. The first two acts were much stronger than the third act, which was a bit too tidy and too far-fetched, even for the genre. Peter Ustinov is just as fun to watch in his second outing as Poirot, but the the real reason to watch this is to see the sparks fly between Diana Rigg and Maggie Smith. Honorable mentions go to Roddy McDowall and Jane Birkin. Last but not least, Cole Porter's music elevates the soundtrack.
