After directing The Sopranos, Steve Buscemi turned to Holland--specifically to the work of Theo van Gogh.
Buscemi's plays jaded journalist Pierre. Once a war correspondent, his editor now assigns him an interview with celebrity Katya (Sienna Miller... who does an incredible job I might add). . They flirt, fight, kiss, and cry. The plot is twisted, for the most part it is filmed in one room- with two people- and it is by no means boring.
Go watch it, I loved it and I keep finding myself trying to fully comprehend it.
Big thanks to Dan for the recommendation.
