Richard Matheson has scripted some of the finest fantasy to ever grace the screen (big and small) and this one, based on the then-unpublished novel by Jeff Rice, took us all by surprise in 1972. I remember the feeling of unease that crept over me as the tale unfolded that night so long ago. I remember a pale man dressed in black, robbing bloodbanks, and the not-so-heroic reporter who dogged his trail, determined to find the truth of the matter, no matter what the cost. I was mesmerised. And greatly satisfied, on all counts. Try watching this one alone, at night, and you'll experience the sheer terror that only the best fright films can engender.
