Henry: Portrait of a Serial Killer is a 1986 American independent psychological horror film directed and co-written by John McNaughton about the random crime spree of a serial killer who seemingly operates with impunity. It stars Michael Rooker in his film debut as the nomadic killer Henry, Tom Towles as Otis, a prison buddy with whom Henry is living, and Tracy Arnold as Becky, Otis's sister. The characters of Henry and Otis are loosely based on convicted real life serial killers Henry Lee Lucas and Ottis Toole.
