Query: A wonderful Agatha Christie book made into a Hollywood piece of trash

Marina Gregg is not the dizzy hare-brained diva portrayed by Elizabeth Taylor. She is a much deeper, sadder character. To see how she should be played, get the BBC version with the superb Claire Bloom in that role. Then you see what a classically trained British stage actress can do. Elizabeth Taylor doesn't come near it. Miss Marple is under-played to perfection by Joan Hickson. The entire cast is uniformly excellent.
