Human Nature is a 2001 comedy drama film written by Charlie Kaufman and directed by Michel Gondry in his directorial debut. The film stars Tim Robbins, Patricia Arquette, Rhys Ifans, Miranda Otto, and Rosie Perez. It tells the story of three people—a writer with hypertrichosis, a man who was raised as an ape away from civilization, and a psychologist who attempts to socialize the ape-man into a civilized member of society and tame his more animal instincts.


In a flashback, Puff, a man who was raised as an ape in the wilderness, makes a testimony to Congress, while writer Lila Jute tells her story to the police. Meanwhile, dead psychologist Nathan Bronfman addresses an unseen audience in the afterlife.
