6. Henry: Portrait of a Serial Killer (1986)
Director: John McNaughton
Loosely based on the life of Henry Lee Lucas, Henry: Portrait of a Serial Killer is a crime thriller that follows the exploits of a crazed killer, played by Michael Rooker. During the film, Henry befriends a fellow prisoner named Otis, and the two go about a savage rampage of random killings with little remorse for any of their crimes.
What this movie does to separate itself from other serial killer dramas is that it never really focuses on cops or an investigation; instead, we’re stuck in the killer’s head the whole time, and after a while it becomes clear that it’s a very dangerous place to be. In the end, even the people Henry calls “friends” and “lovers” don’t stand a chance against his sick mind.
