Wargames (1983)
An iconic movie for geeks. We are introduced to the W.O.P.R. computer that enjoys thermonuclear war. Oops. A precocious teenage hacker discovers too late that a 'game' he starts playing with the WOPR is really prelude to nuclear war.
"Shall we play a game?"
Joshua, aka WOPR
The iconic line was picked up again by Natasha Romanoff in Captain America: The Winter Soldier
