In 2007, Harris wrote a screenplay of his novel "Pompeii" for director Roman Polanski. Harris acknowledged in many interviews that the plot of his novel was inspired by Polanski's film "Chinatown", and Polanski said it was precisely that similarity that had attracted him to "Pompeii". The film, to be produced by Summit Entertainment, was announced at the Cannes Film Festival in 2007 as potentially the most expensive European film ever made, set to be shot in Spain. Media reports suggested Polanski wanted Orlando Bloom and Scarlett Johansson to play the two leads. The film was cancelled in September 2007 as a result of a looming actors' strike.
