No Way Out (1987)

Factual error: The Pentagon is the largest office building in the world. It has seven floors, 28 kilometers of corridors and 620,000 square metres of office floor space. The idea that the entire building could be searched in one afternoon by six people is beyond absurd. If those six people could search an average of one office every five minutes and they worked twenty four hours a day, seven days a week they'd get through the whole building in 89 days and 15 hours. I don't think the punter they are looking for has a lot to worry about.

Factual error: 26,000 people work in the Pentagon. If they were to all file past one person so he can try to pick out a crime suspect, and each person takes just two seconds to walk past, be checked, eliminated and sent on their way, it will take fourteen and a half hours to clear the building. There are going to be some very unhappy people at the back of the queue.

Factual error: Kevin Costner gets on the Washington Metro in Georgetown. There is no metro stop in Georgetown. Also when the doors of the metro close, it's not the doors of the Washington Metro - it's a Baltimore Subway Station and Train.

Tom Farrell: Let's get out of here.
Susan Atwell: My date's not going to like that much. But what the hell, his wife will be delighted.

Scott Pritchard: Tom is the one who saw you at Susan's. He's known about you all along, isn't that right? We do know what that means. If Commander Farrell is the man who was with Miss Atwell, then Commander Farrell is the man who killed Miss Atwell. And we know that the man who killed Miss Atwell is Yuri. Therefore, Commander Farrell is Yuri, quod erat demonstrandum.

Tom Farrell: Well, then, Brice is in an impossible situation. We should just call in the FBI.
Scott Pritchard: Don't be an idiot. Do you realise the magnitude of the scandal? The Secretary of Defense and a Soviet agent sharing the favors of a murdered whore.
