Knife of Ice is quite a strange movie in some respects. Released in 1972 at the tail end of the giallo craze, it could be expected that this would be an entry in the sub-genre that emphasised the sex and violence like most other entries from that year. When you also consider that its director is Umberto Lenzi who was responsible for several highly exploitative movies and who is to subtlety what Mr T is to Shakespearean acting, you would be forgiven for thinking Knife of Ice would be a classic style bloody and sleazy murder mystery. Well, as anyone who has seen this film can confirm that simply is not the case. This is a giallo in the late 60's style. All of the murders are committed off screen and there is no nudity whatsoever. The only bit of outrage is the opening credit sequence which shows a fairly graphic bull fight, so Umberto did at least incorporate one of his more notorious traits – animal slaughter - into this one at least.
The film seems to be a reworking of the 1946 chiller The Spiral Staircase. It has a fairly similar basic plot-line. The central character is a mute woman who lives in a large affluent family home. There is a serial killer on the loose and a cast of red herrings to complicate matters. Caroll Baker (So Sweet, So Perverse) stars as the mute, while Evelyn Stewart (The Case of the Scorpion's Tail) appears too in a role that sadly has little screen-time. It's certainly a professional enough effort with some suspenseful moments but on the whole it is a little too restrained for its own good and it pales in comparison with other gialli released around the same time.
