Movie Preview: Michelle Williams, Ewan McGregor in Incendiary Got your tissues handy? Because this trailer's probably going to make you sad. Starring Michelle Williams and Ewan McGregor, Incendiary (based on a novel of the same name) is the story of a woman who loses her son and her husband in a suicide bombing, an event made more traumatic by the fact that she witnesses the attack on TV with the man with whom she's having an affair.
