Umberto Lenzi the Italian director that brought us "Cannibal Ferox" and "Eaten Alive!" also brought us a cutting edge (no pun here) murder mystery, "Knife of Ice" from 1972. The title is derived from an Edgar Allan Poe quote, which is appropriate as this film utilizes many Poe themes. Like Poe works, this Lenzi film has lots of dead beautiful women. Carroll Baker ("Giant" and "Baby Doll") was more than 40 years old when she starred in this film, though her appeal as a sex object was still in full force. Ms. Baker would then turn in a striking performance as a mute damsel, quite helpless, and in much peril.
