It stars Daniel Craig as Heisenberg.

I used to own the DVD, but somehow it disappeared. I haven't seen it in many years.

The science is presented at a low level and in a fairly cutesy way - I doubt that a conversation between Bohr and Heisenberg involved the explanations of fission for the benefit of the popular audience - and one has to sit through, in the introduction, with the tiresome smug "wisdom" from Michio Kaku, he of the great haircut, but as art, the film's not too bad.

After the play was written and produced, it was discovered among the real Neils Bohr's papers, an account of the actual event that was not flattering to Heisenberg.
