Sandy haired, authoritarian looking UK born actor who achieved minor cult status via his appearance as "Greg Preston" in the cult BBC TV series Survivors (1975) about a genetically engineered germ plague that nearly wipes out the entire population of the earth, plus McCullough also starred in several notoriously violent Italian made horror films of the early 1980's that were part of the "video nasty" controversy within the UK. McCullough was the male lead in the Romero inspired L'enfer des zombies (1979) aka "Zombie Flesh Eaters" directed by Lucio Fulci, he was back battling more living dead in La terreur des zombies (1980) aka "Dr Butcher MD" directed by Marino Girolami, and then McCullough took on interplanetary invaders in the Alien - Le 8ème passager (1979) rip-off Contamination (1980) directed by Luigi Cozzi.
