text: This is indeed one of the weakest films based on Agatha Christie's work, a lifeless, muddled mystery that clearly lacks the grace (and the budget!) of its predecessors ("Death On The Nile", "Evil Under The Sun") and Donald Sutherland is a pale shadow of Peter Ustinov as far as screen detectives go (of course, he is playing a character much less interesting than Poirot). The film manages to coast as far as it does on the strength of Christie's plot alone (all her plots have a certain amount of inherent interest), but the direction is hopelessly flat. (*1/2)
