Some of the reviews assert that this was a poor version of the play it is based on, but for those of us who didn't get to see the play at least we have this. In reality these arguments had been going on among physicists for several years. It is particularly strange that this British film talks about America possibly building a bomb but in fact in 1941 Britian was was ahead in the race. Ultimately it was American money and technology, not physics, that won the race for the bomb. The film was right, however, that Germany never even tried, perhaps knowing that they did not have the resources necessary. Maybe this is what Heisenberg was trying to say?
