the last man on earth (1964)

aka L'ultimo Uomo Della Terra. Naked Terror. Night People. The Night Creatures. Vento di morte. Wind of Death.
As in the previous post Dr Robert lives in a city in ruins. Alone, the last survivor of a terrible virus that he alone seems to be immune to. He searches for survivors with no success, and continuing his research to find a cure. Whilst hiding from the mutant victims that come out at night and seek to kill him.
Vincent Price gives a muted and poignant performance as a man struggling to survive, conveying his loneliness and desperation in this low budget Italian offering. Much darker and infinitely better than the Will Smith version.
