You can't really go wrong with David Lean adapting Noël Coward in a film about poor old Rex Harrison ("Charles") and three on-form women: two of whom he married - Constance Cummings ("Ruth)" and Kay Hammond ("Elvira") and the other is the source of most of his woes - spiritual medium Margaret Rutherford ("Madama Arcati"). Right from the start, the pace of the dialogue is witty and engaging. Harrison - who can be terribly wooden on occasion, is well up for this spiritual lark as a seance at his home - under the supervision of the dotty Rutherford - releases his former wife "Elvira" back into his life where only he can see her; and she decides to cause the maximum amount of mayhem for her former husband and his new wife "Ruth". The nature of the story keeps the cast small, and the action is end-to-end with plenty to make you smile as well to appreciate the dynamics of wedded "bliss". It's a dream - though more of a nightmare for Rex!
