One of my top 10 favorite movies. i always like Detective Poirot series and this movie is one of the best and maybe most complicated ones (number of suspects and misleading parts). Poirot happens to be on a train which a mafia member is on it and almost whole cabin have planned to be on that train same night to murder him. Along the movie when Poirot interviewing suspects and you can enjoy his funny acts and talks, a non criminal story happening, introducing western countries nations from Agatha Christie point of view. We got American, Swedish, German, Russian, Hungarian, French, Italian, Greek, Scottish, ... which is quite entertaining and a great job (you be agreed with writer or not, you still we give her many points). Me myself, enjoyed the under layer nations behavior more than confusing criminal case, not that after ending conclusion i still find it difficult to understand, but number of suspects and that actually are were involved almost equally, was quite different compare with other same category movies. Beside the murder case and different nations behavior, at the end, you got to make a moral decision, to agree with Poirot to call the case closed as the victim was indeed a brutal murderer or leave the case to police ( Yugoslavian) or as you can say "to the law".
