Mysterious Skin is a 2004 coming-of-age drama film written, produced, and directed by Gregg Araki, adapted from Scott Heim's 1995 novel of the same name. The film tells the story of two pre-adolescent boys who both experienced sexual abuse as children, and how it affects their lives in different ways into their young adulthood. One boy becomes a reckless, sexually adventurous sex worker (played by Joseph Gordon-Levitt), while the other (Brady Corbet) retreats into a reclusive fantasy of alien abduction.

Mysterious Skin premiered at the 61st Venice International Film Festival in September 2004, moving into wider distribution in May 2005 without a rating. It grossed $2.1 million at the box office and received critical acclaim. Psychologists have praised Mysterious Skin for its accurate depiction of the long-term effects of child sex abuse.
