Martin

I’m a big George Romero fan. I was excited to find his movie, Martin, on YouTube. It’s (sort of) a vampire film and very different from a lot of his other work.

Young Martin (John Amplas) is entirely convinced that he is an 84-year-old blood-sucking vampire. Without fangs or mystical powers, Martin injects women with sedatives and drinks their blood through wounds inflicted with razor blades. After moving to Braddock, Penn., to live with his superstitious uncle (Lincoln Maazel), who also believes Martin is a vampire, Martin tries to prey exclusively on criminals and thugs but stumbles when he falls for a housewife (Sara Venable).
