Henry: Portrait of a Serial Killer (1986)
He's not Freddy. He's not Jason. He's real.
Henry: Portrait of a Serial Killer, loosely based on the case of Henry Lee Lucas, a confessed serial killer, is a terrifyingly journey into the twisted life of a murderous psychotic. As the blank-eyed Henry drifts from place to place, he selects victims at random, slaughters them, and captures the brutality on videotape. When he is joined by his deranged roommate, a loudmouthed ex-convict named Otis, the almost unfathomably malevolent acts multiply.
