Kevin Costner at least tried to do an accent in this movie, which probably means he got a new agent, a yes man that didn't bother to give him the advice that doing believable accents isn't his thing. It's almost like listening to your average Brit trying to sound like an American and completely overdoing it.

Do we really sound that exaggerated to them?

Who cares, ignore the above, it's still a good movie... despite Costner's accent. Or, possibly, in spite of it.

It trashes Dean Achenson, and as a historian the only thing I like to see MORE than Dean getting his just deserts is Allen Dulles getting his... and it throws a jab at that a**hole too. In 2000 that would have been seen as pure liberal honesty, but now it sort of comes across as far right. I mean the movie is literally about avoiding Nuclear War with Russia as the entire Democratic party and the progressive movement seem to want to push us closer and closer to it.

It's one of the better political films you can see, and it builds the pressure to the point where you are terrified that the world could end despite the fact it has long come and gone. And the shift from Jack and Bobby to Ken O'Donnel, a humble appointment secretary is probably one of the best approaches and best ideas any Historical Drama has ever had.

Start to finish it is one of the best political thrillers of all time.
