William Castle's 1950s camp classics 'The Tingler' and 'House On Haunted Hill' are lots of fun, and highly recommended to all horror fans with a strong sense of the absurd. I expected 'Homicidal' to be a similarly silly but entertaining affair, especially as it was also written by Robb White, but was quite surprised at just how dark and effective it was. Apart from Castle's typically hammy introduction, and the "fright break" towards the climax (a not too dissimilar idea to the one Gaspar Noe used several years ago in his shocking 'I Stand Alone'!), 'Homicidal' is nowhere near as gimmicky and tongue in cheek as most of Castle's best known movies. Maybe that is why it is rarely mentioned when his work is discussed. Too bad, to me it is one of his most interesting and effective shockers. While obviously inspired by 'Psycho', and made on a shoe-string budget with variable acting, I was quite impressed by it. The opening sequence is memorable - a beautiful blonde (Jean Arliss) checks in to a swanky hotel, and offers a shocked bellhop cash to marry her, assuring him that the marriage will be annulled immediately after the event. He is puzzled but agrees, and at the ceremony the next day the mysterious blonde quite unexpectedly murders the JP! We then follow her to a house where she looks after an elderly woman (Eugenie Leontovich) who is mute and confined to a wheelchair after a stroke. The old woman is obviously terrified of her, but is unable to convey this to any visitors to the house. Pretty soon we meet the other characters, and learn of a $10 million inheritance, and things start to get real interesting... I won't elaborate any further for fear of spoiling the plot. The major twist will no doubt be guessed by the viewer fairly quickly but there are still some surprises and shocks in store. Arliss (actually Joan Marshall) gives an intriguing performance. Why she didn't go on to bigger and better things after this is beyond me. I urge fans of Castle's better known movies to check out this little gem. I really enjoyed it and highly recommend it to all fans of b-grade thrillers and horror movies.
