Continuity mistake: When everyone is trying to get Joshua/WOPR to stand down from launching its own missiles, McKittrick's assistant Paul is standing with the rest of the group, but then there is a quick shot of Paul looking at the WOPR and then within seconds Paul is overheard saying "must be caught in a loop" as if he's standing beside everyone again.

Revealing mistake: When David begins to play against the WOPR computer, the images on the war room screens show various tactical movements by other countries. These are the same images shown the first time the war room is seen.
