"Night Must Fall," which was originally a play by Emlyn Williams, contains three fantastic roles for actors, and as a film, it has been beautifully cast, directed (by Richard Thorpe), and photographed. Set in an English cottage in a village that borders a forest, Rosalind Russell lives with her horrid, verbally abusive aunt. Along comes Danny, basically brought into the household to be spoken to about a promised marriage to one of the maids in the house. Danny is a sexual opportunist, a murderer, and a psychopath who can hone in on what each person he meets needs and wants. He soon becomes charmingly indispensable to the aunt. The Russell character senses his black soul but is attracted to him nonetheless, and he knows it. What transpires is an intriguing mystery and psychological drama.

Robert Montgomery was a wonderful actor, adept at many kinds of roles but most often cast in the light comedies so often made in the '30s. Here he is fantastic - a charming, frightening liar with a huge ego who thinks his crafty mind will win in the end. Russell gives a beautiful, underplayed performance as an unhappy young woman, dating a man she's not sure she loves, attracted to this stranger and to the possibility of something interesting happening to her. Dame May Witty is great as an abrasive shrew.

This is one of those gems - and doesn't Hollywood know it, they've remade it enough - but it's a real tour de force for the right actors. A winner.
