Blackrock is a 1997 Australian teen drama thriller film produced by David Elfick and Catherine Knapman, directed by Steven Vidler with the screenplay by Nick Enright. Marking Vidler's directorial debut, the film was adapted from the play of the same name, also written by Enright, which was inspired by the murder of Leigh Leigh. The film stars Laurence Breuls, Simon Lyndon and Linda Cropper, and also features the first credited film performance of Heath Ledger. The film follows Jared (Breuls), a young surfer who witnesses his friends raping a girl. When she is found murdered the next day, Jared is torn between revealing what he saw and protecting his friends.
