CLIP DESCRIPTION:
David (Matthew Broderick) insults his condescending teacher in front of the whole class.
FILM DESCRIPTION:
Once more, a wise-guy teenager tries to prove he's smarter than any adult-and nearly destroys the whole world in the process-in Wargames. Computer-game aficionado Matthew Broderick inadverently taps into a hush-hush Pentagon computer, then proceeds to inaugurate his favorite game, "Global Thermonuclear War". What we know, but Broderick doesn't, is that the Pentagon, hoping to eliminate the chancy "human element" in the event of an actual war, has given its computer total, irreversable control over the launching of nuclear weaponry. Broderick and government official Dabney Coleman race against time to reverse the computer's resolve to send bombers to Russia. Wargames scored a hit, especially with teenage filmgoers.
