Blackrock is a 1997 Australian drama thriller film directed by Steven Vidler and written 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.
