Just "discovered" this movie...
And I must admit that, even though I figured out the ending pretty early in the movie, it is well worth watching more than once. The actors are amazing; esp the big three: Charles Laughton, Marlene Dietrich, and Elsa Lanchester. I don't think I've ever seen them better. This is definitely going on my "must own" list.
[Please forgive me this one time if I happen to disagree with you. It won't happen again -- well, probably won't...]
