His own brilliant directing career has been marked by similarly grand ambitions, and he is unique in having premiered all of his features - from the highly styled The Element of Crime to the digital-video-originated The Idiots - at the Cannes Film Festival. Trier is a rare item in contemporary cinema, a restless innovator and polemicist, as his participation in the back-to-basics Dogme95 movement attests; and these conversations with Stig Bjorkman, author of Bergman on Bergman and Woody Allen on Woody Allen, trace the evolution of his career and thought in a manner that is both astonishingly detailed and engagingly humorous.
