William Devane gives a compelling performance as President John F. Kennedy in this dramatization of the Cuban Missile Crisis. Based partly on Kennedy's book Thirteen Days, the film recounts the 13 days in October 1962 that nearly led to nuclear war. Co-stars include Martin Sheen as Attorney General Robert F. Kennedy, Ralph Bellamy as U.N. Ambassador Adlai Stevenson and Howard Da Silva as Soviet Premier Nikita Khrushchev.
