Fascinating low budget horror thriller with quite the talent pedigree. Made in 1972, it was directed by John Hayes, an interesting guy who made a variety of unusual low budget films during the 60s and 70s. He cowrote the screenplay with none other than David Chase, the genius behind Northern Exposure, The Rockford Files, Kolchak: The Night Stalker, I'll Fly Away, and of course The Sopranos. Two great character actors in the lead--William Smith and Michael Pataki--help make this a cool, rare vampire flick. Check it out!
