 The film has one of the longest, most complex uninterrupted scenes  ever made. In the scene, where two actors talking against a  background, 16 of the 17 planes, four groups of four aircraft, took  off at the same time. As the scene progresses, the actors entered a  building and the same planes were seen through the window, climbing  into formation. The problem was, for every take, the production  manager has to call the planes back and made to take off again for  every take of the particular scene. This was done four times.
