Grand Theft Parsons is a 2003 film based on the true story of country rock musician Gram Parsons (played by Gabriel Macht), who died of an overdose in 1973. Parsons and his road manager, Phil Kaufman (Johnny Knoxville), made a pact in life that whoever died first would be cremated by the other in what was then the Joshua Tree National Monument, an area of desert they both loved and cherished.
