Knife of Ice (1972)

Knife of Ice (Il coltello di ghiaccio), released in 1972, was the fourth movie Umberto Lenzi made with star Carroll Baker and it’s a bit of a change of pace.

The first three movies are what I describe as proto-gialli - they have some of the style and feel of the later gialli but there are major differences. They’re stylish erotic thrillers that lack the blood and gore of the full-blown giallo. Knife of Ice is an interesting hybrid. Structurally it’s a giallo but in style and tone it’s a proto-giallo. And it has hints of the supernatural.

This was a Spanish-Italian co-production set in Spain. The bullfight credits sequence seems to have no connection to the rest of the movie but in fact it includes a clue.

Umberto Lenzi co-wrote the screenplay with Antonio Troiso. The original inspiration for this movie was Robert Siodmak’s 1946 classic The Spiral Staircase, a movie for which Lenzi had enormous admiration. Lenzi and Troiso made major changes to the plot so if you know how The Spiral Staircase ends that won’t help you in guessing the ending of Knife of Ice. Lenzi did not want to do a remake but rather a totally different movie taking the 1946 movie as a jumping-off point.

Martha Caldwell (Carroll Baker) arrives at her uncle’s home in Spain with her cousin and best friend Jenny Ascot (Ida Galli). Her uncle suffers from a severe heart complaint. He’s being treated by Dr Laurent (Alan Scott). It’s not quite clear if Dr Laurent is Martha’s boyfriend but they’re obviously close.

Then two murders take place. It seems there is a serial killer on the loose. The police find occult symbols and evidence of a Black Mass having taken place. There are signs that a satanic cult might be active. Two of the central characters have a great interest in the occult. There’s a crazy guy hanging around and he seems to be on the scene when a murder takes place. Inspector Duran (Franco Fantasia) certainly thinks he could be dealing with satanic cult murders.

Then the plot twists start to kick in. Regardless of the identity of the murderer or the motive there’s no doubt that Martha has been marked down for murder.

There’s no shortage of sinister suspects. There’s Martha’s occult-obsessed uncle, there’s the slightly creepy housekeeper, there’s the weird satanist guy, there’s the doctor, there’s the black-clad chauffeur.

Like a full-blown giallo this movie has multiple murders but there are no spectacular murder visual set-pieces. Lenzi is more interested in the atmosphere and in building a sense of dread. We feel that Martha is in great danger but we don’t know why and that adds to the dread.

This movie not only lacks gore, it also has no nudity or sex. That probably hurt it at the box office. Lenzi’s three previous movies with Carrol Baker were sexy thrillers and they were huge hits. Knife of Ice enjoyed much more modest commercial success.

Those earlier Lenzi-Baker movies were very stylish films with an atmosphere of glamour and decadence. In this film Lenzi is aiming for a very different feel. He throws in quite a few gothic horror tropes and the overwhelming tone of the movie is gothic. He keeps us in doubt as to whether it might turn out to be gothic horror or merely gothic melodrama but the gothic vibe is strong. There are plenty of moody creepy fog-bound scenes. It’s obvious that Lenzi was determined not to get stuck in a rut. A couple of years later he would turn the giallo genre upside-down and inside-out with his brilliant Spasmo.

Martha is mute. She isn’t deaf. She experienced an appalling shock as a child (seeing her parents killed in a train accident) and she hasn’t been able to speak since. It’s a challenging role for an actress but Carroll Baker does an excellent job.

Alan Scott is very dull as the doctor but the supporting players are very good.

Knife of Ice is low-key but enthralling and I enjoyed it immensely. Highly recommended.

Severin’s Blu-Ray includes something increasingly rare these days - genuinely worthwhile extras. There’s a longish and very informative interview with Lenzi and a very perceptive video essay by Stephen Thrower.

I’ve also reviewed the first three Lenzi-Baker collaborations, Orgasmo (AKA Paranoia, 1969), So Sweet...So Perverse (1969) and A Quiet Place To Kill (1970).
