Dave Stewart has scored the documentary Unlawful Killing, which premiered at the Cannes Film Festival last Friday. The film about the deaths of Princess Diana and Dodi Fayed on August 31, 1997 is directed by British actor and filmmaker Keith Allen (Trainspotting, Shallow Grave). The movie mixes interviews with recreations of some of the key moments from the official inquest. According to the film’s press release,  the questions the film asks will inevitably shake the public’s perceptions of how Diana and her partner Dodi Fayed died. Guest contributors on the film include Tony Curtis, Howard Stern, Kitty Kelley, Mohamed Al Fayed, Piers Morgan and Michael Mansfield QC. The project marks Stewart’s first feature film credit since the 2004 remake of Alfie, on which he collaborated with Mick Jagger and composer John Powell. The musician/songwriter/record producer and composer, who is best known for his work with Eurythmics has previously scored a number of films, including Ted Demme’s Beautiful Girls and Robert Altman’s Cookie’s Fortune.
