As a history student and a Kennedy fan this film was a must for me!! I was slightly dubious before watching this as to its historical accuracy but this film is by no means inaccurate. Yes there are a few embellished details but all in all this is almost accurate, The role of O'Donnell has been enhanced but the roles of Jack and Bobby Kennedy have been in no way exaggerated. They really were this important in pretty much saving the world from nuclear war!!
This film is a taut, gripping thriller, which even though most viewers will know the outcome of the crisis, still has you sat on the edge of your seat wondering what will happen and marvelling at how close we actaully came to nuclear war. The performances of the main stars has to be admired as all gave fine performances. Costner was fine as O'Donnell, though his accent was a little annoying. The real stars of the film, despite Costner's top billing, were Greenwood and Culp. Greenwood had quite obviously painstakingly studied tapes of Kennedy as his mannerisms were spot on and Culp as Bobby was completely fantastic. I had to look twice to check it wasnt actually Bobby Kennedy he had the mannerisms, attitude and even the voice off perfectly.
All in all this is a highly enjoyable film about a fascinating time that hasnt been ruined by the embellishments and fantascism of Hollywood! Well worth a look!
