The DVD has a commentary and they talk about the scenes that could not be reconstructed and had to be rewritten from conjecture. The movie is about the McCarthy era and people often were paranoid and secretive.

The commentary does not say much about the slant they give to the story. Naturally, it does have a slant.

The main reason I brought it up is that the movie also addresses the role, the responsibilities and the sponsorship, of the media. It is an entertaining way to get some new ideas about a relatively dull subject.
