According to Wikipedia: "Lawrence George Cohen was an American screenwriter, producer, and director of film and television, best known as an author of horror and science fiction films — often containing police procedural and satirical elements — during the 1970s and 1980s, such as It's Alive (1974), God Told Me To (1976), It Lives Again (1978), The Stuff (1985) and A Return to Salem's Lot (1987). He originally emerged as the author of blaxploitation films such as Bone (1972), Black Caesar and Hell Up in Harlem (both 1973). Later on, he concentrated mainly on screenwriting, including Phone Booth (2002), Cellular (2004) and Captivity (2007).
Early in his career, he was a prolific television writer, creating series such as Branded, Blue Light, Coronet Blue, and The Invaders. In 2006, Cohen returned to the directing chair for Mick Garris' anthology series Masters of Horror, directing the episode "Pick Me Up". In 2017, he was the recipient of a Lifetime Achievement Award from the Fantasia International Film Festival."
