Natural Born Killers was based on a screenplay written by Quentin Tarantino, in which a married couple suddenly decide to go on a killing spree. Tarantino had sold an option for his script to producers Jane Hamsher and Don Murphy for $10,000 after he had tried, and failed, to direct it himself for $500,000. Hamsher and Murphy subsequently sold the screenplay to Warner Bros. Around the same time, Oliver Stone was made aware of the script. He was keen to find something more straightforward than his previous production, Heaven & Earth (1993), a difficult shoot which had left him exhausted.I might have seen natural born killers actually. Or some of it. Him trying to compete with Tarantino.
