This movie definitely reinforces my policy of watching a movie before reading the book that it is based on. This movie is fine if you watch it and then read the book, almost like a warm up for the actual story. Rue McClanahan and Edward Woodward save this movie! Without their believable quirkiness so much of this movie would have been both over the top and silly. They keep it moving in the right direction when at times it can feel like it's trying to veer off course a little. The book itself is Wonderful! One of my favorites of Agatha Christie's. But I don't know if my review of the movie would have been as favorable if I'd gotten my hands on the book first.
