Copenhagen (PBS Hollywood Presents)
This 2002 film, based on the play by Michael Frayn, imagines what might have  happened between the physicists Niels Bohr (Stephen Rea,The Crying  Game) and Werner Heisenberg (Daniel Craig,The Road to  Perdition) on a particular night in September of 1941. Heisenberg was  collaborating with Nazis in Germany; Bohr, a Jew, was living in occupied  Denmark but had contact with physicists on the Allied side. Something in  this meeting destroyed their longstanding friendship; Frayn envisions  their ghosts--and that of Bohr's wife, Margrethe (Francesca Annis,Dune)--reliving, arguing, and fantasizing about a conversation in  which an innocent topic like skiing could slide into a dangerous  discussion of physics and politics. This skillfully woven and well-acted  conversation, far from being a static talk-fest, has all the dynamism of a  psychological thriller. Our intentions, like the particles at the heart of  physics, can never be known for certain.--Bret Fetzer
