- The Pentagon forbids camera crews near the entrances to the complex, due to security reasons. Still, Director John Frankenheimer wanted a shot of Kirk Douglas' character entering the building.

The salutes Douglas received in that scene were real as the guards had no reason to believe it was for a movie!
