The film is titled "Oppenheimer", not "How We Made The Bomb". It is based on the book "American Prometheus", which is a biography of Oppenheimer. I plan to watch it, and expect that it will be mostly about the man. BTW, the saga of Oppenheimer and his reputation has seen much evolution. I recall, back in the year 1969, seeing a play "In the Matter of J. Robert Oppenheimer" (I was 14 or 15). It's tied into the whole McCarthy era which has also undergone many changes in interpretation over the years.
