The last film by underrated director Alberto De Martino ("The Antichrist", "The Killer is on the Phone") is a truly suspenseful but incomprehensibly neglected giallo, containing pretty much all the trademarks that makes this Italian horror sub genre so magnificent and addictive to the fans. There are some very disturbing themes (child abuse, phony priests), loads of creepy moments, plot twists left & right, outstanding music and  last but not least  a handful of really sadistic murder scenes! Especially the opening sequence, which is some kind of prologue, is a powerful piece of horror! What is it about ordinary child dolls that make them so creepy? When the anonymous man, dressed up like a priest, assaulted a little girl and the broken head of her doll bounced down a flight of stairs, it really sent cold shivers through my spine! Years later, the young girl from the prologue is an adult woman bound to a wheelchair. She inherited a lot of money but uses her fortune to stimulate fellow handicapped people to practice sports and to remain positive-minded. She  Joanna  falls in love with her personal coach and they get married right away. Naturally, he's only after her money and starts terrorizing Joanna by making her relive the childhood trauma that crippled her. The repeated images of a sinister looking priest, guided by eerie tunes and a nursery rhyme, provide "Formula for a Murder" with a ton of genuine scares and Alberto De Martino's directing is very resolute. The acting is quite competent, with David Warbeck ("The Beyond", "The Black Cat") in a glorious greedy villain role. Due some plot holes and a lack of originality, this movie might not be able to compete with Italy's best horror efforts, but it definitely deserves more attention. Many formerly obscure and unknown Italian gialli received marvelous DVD-releases and, hopefully, "Formula for a Murder" will be given the same treatment really soon. In the meantime, good luck tracking this baby down!
