This has got to be one of the best covers I have found. Wasn't the subject matter exciting enough? Wasn't the Cuban Missile Crisis enough? Wasn't the closest the world has come to nuclear annihilation enough?
Apparently not.
Now I don't know a lot about history, but I don't think President Kennedy ever sat in the Oval Office with gun in his hand. Even if he did, do you think it would have such a large silencer on it? And I don't remember Kevin Costner's character, Kenny O'Donnell, ever carrying a gun in this movie. Possible that it's from a different Costner film (or just spliced on, either is likely).
