Brace yourself for one of the most unsettling films ever made. Henry: Portrait of a Serial Killer (1986) is a raw, unflinching look into the mind of a drifter whose calm demeanor masks a terrifying reality. Loosely based on real-life killer Henry Lee Lucas, this controversial cult classic by John McNaughton strips away Hollywood gloss to deliver a haunting portrait of violence, detachment, and moral decay. Not for the faint of heart.
