Miranda (1948)

There’s a dreadful shortage of men below sea. With his wife Clare (Googie Withers) uninterested in fishing, Dr. Paul Martin (Griffith Jones) goes on holiday in Cornwall.  There he snags mermaid Miranda Trewella (Glynis Johns) and is pulled into the water. She keeps him prisoner in her underwater cavern and only lets him go after he agrees to show her London. He disguises her as an invalid patient in a wheelchair and takes her to his flat for a month-long stay. Clare reluctantly agrees to the arrangement, but gets him to hire someone to look after their house guest and he selects Nurse Carey (Margaret Rutherford) for the eccentric nature that previously caused him to get rid of her and takes her into his confidence. To Paul’s relief, Carey is delighted to be working for a mermaid as she always believed they exist. Miranda’s seductive nature earns her the admiration of not only Paul, but also his chauffeur Charles (David Tomlinson), as well as Nigel (John McCallum), the artist fiancé of Clare’s friend and upstairs neighbour Isobel (Sonia Holm) arousing the jealousy of the women in their lives. Clare starts to follow her instincts and starts reading up on her suspicions. Nigel breaks off his engagement, but then he and Charles discover that Miranda has been flirting with both of them ….  You’ve hated me ever since I set tail in this house. The delightful Johns has fun as the beguiling mermaid who insinuates herself into the life of a doctor living quite the de luxe life in his well appointed London apartment with his lovely wife Withers. And then she drives every man mad with desire. There are lovely moments when she can’t help herself – snacking on the goldfish straight from the bowl, scarfing cockles at the fish market and depriving a sea lion of his lunch on a trip to the zoo. Witty and surprising, this wastes no time in introducing Johns – two minutes – and once she fishes Paul out of the water and into her cave she wastes no time in telling him she had to throw the last two men back because their legs were too short. She has a disarming way of critiquing men’s physiques to their face. Withers plays opposite offscreen husband McCallum while the redoubtable Rutherford has an amusing scene in a museum with a mummy and off-screen husband Stringer Davis. Witty, charming fluff with Johns as bewitching as ever as the flirty fish out of water and some timely references including the novel Forever Amber – which plants the suggestive conclusion. Adapted from his play by Peter Blackmore with additional dialogue by Denis Waldock, this was produced by Betty Box and directed by Ken Annakin. Tail by Dunlop. There is a sequel, made 6 years later, Mad About Men. If you ask me there’s something very fishy about this case
