Rawhead Rex is a 1986 Irish fantasy horror film directed by George Pavlou, produced by Kevin Attew and Don Hawkins, and written by Clive Barker, based on his short story of the same name. The story had originally appeared in Vol. 3 of his Books of Blood series. The film focuses on a monstrous pagan deity's bloody rampage through the Irish countryside, with the title alluding to the folklore monster Rawhead. Pavlou and Barker had previously worked together on Transmutations.
