Although the film's story-line is fiction, the facts of this low-key thriller are based on truth and provide a 'what if' scenario that keeps the viewer engaged. The director, Peter Yates, captured a style of filming and cinematography that makes it feel almost like an undiscovered Hitchcock film. Kelly McGillis is believable, although perhaps not quite the typical Hitchcock blonde, and Jeff Daniels may sound a bit too modern in some of his speech inflections, but Everything else about this film reeked of authenticity, from the genuine feel of the sets and authentic but real clothing, to the dialogue. I don't know why this film rated only a middlin score with viewers - perhaps they were expecting more of an action thriller,rather than the political intrigue style of thriller that it is.
