BEWARE, MY LOVELY is an interesting little psycho-thriller made before that genre even existed. It's essentially a two-hander (with a few peripheral characters for good measure) in which housewife Ida Lupino is menaced by handyman Robert Ryan. The latter is extremely good when playing up the quiet menace and madness of his character; he's typically cast as a hero but is just as effective on the other side. Lupino is assured and courageous throughout. The film's suspense is in short supply, and it suffers from a huge non-ending, but for fans of either star or those looking to trace the development of this sub-genre of film it's worth a look.
