This is a film that I have viewed again and again and is always fun to watch. From the opening credits of 1940's style illustrations of the romanticized golden era of cruise ship travel set to a sumptuous smooth jazz score, the movie is steeped in mysterious atmosphere. The film was based on a radio play from the 1940's. It stars Lindsay Wagner as Lindsay Gates, a widow who has just gotten married for the second time and is setting out on her honeymoon aboard the Queen Mary. However her ideal honeymoon goes horribly wrong, when she cant find her husband. And when she tries to locate him, no one remembers seeing him. When the truth about Lindsay's first husband's death is revealed, her seemingly unstable mentality convinces everyone that she is crazy and she made up a story about a fictional husband. Parinoid that she can't trust anyone, she sets out determined to find her husband and prove she isn't insane. She begins a desperate investigation of her own that leads her on an intriguing mysterious path of twists and turns that leads her to the truth. Is she really crazy?, did something really happen to her husband? or is it much worse?, this story will have you guessing and totally captivated to the very end. The film has a very vintage feel, and is superbly written and acted. the music is sumptuous and the costumes, hair and makeup definitely complete the feel of a true 40's mystery movie. The incredible use of the Queen Mary ocean liner truly makes the movie and transports the viewers back in time to the fabulous glamor days of 1st class transatlantic travel. The supporting cast is superb with the fabulous Angie Dickenson as Lindsays apparent shipboard friend. Everyone seems to be hiding a secret or possible involvement, and the twist ending is very satisfying. The film definitely has rewatchability and i strongly recommend this to film noir buffs, mystery fans, or people who love movies set on cruise ships. Sit back, relax and get totally involved with the shady cast of characters, mysterious plot and intrigue.
