"If you dream of one day working with Polanski or Terrence Malick or Stephen Frears, what do you do? 'Oh no, I'm a bit tired?' You just do it."
The Malick project, "The Tree of Life," is one of the most anticipated films of 2011, and Desplat began work on it as far back as 2007. As usual in Malick films, the score shares space with classical cues, in this case Ligeti and Berlioz, among others. Desplat also had to work largely without the benefit of images. He describes his contribution as orchestral, meditative and trance-like.
"(Malick) always told me that the music should be like a river flowing through the film," says Desplat, "and that's what I tried to achieve -- something that flows and never stops, very alive and fluid. He just wants you to create something that maybe he hasn't thought about."
