Amazon.com video review: John F. Kennedy lived long enough to see this Hollywood account of his Navy career and his heroism following a ruthless attack by a Japanese ship on his small patrol craft. Cliff Robertson is an amiable choice to play Kennedy, though one won't find a lot of the late president's mannerisms in his performance. The key battle sequence, which finds Kennedy and his crew bloodied and battered while trying to stay alive in shark-infested waters, makes a big impression on young viewers. --Tom Keogh
