In ”True West,” Austin, a successful screenwriter, is surprised by a visit from his brother Lee, who has come to steal some items from their mother’s house, which Austin is house-sitting. The rivalry between the brothers comes to a head when Lee pitches an idea for a film to a producer who has come to hear about Austin’s latest work, and the producer becomes very interested – provided Austin helps Lee to write the script. Things between him and Austin gradually reach a fever pitch as they work on the screenplay, leading to a surprising, but perhaps inevitable, conclusion.
