Production Note: This could be considered movie trivia, and though I've been aware of this minor little issue for years, I've never thought about it long enough to mention it here. Basically, in scenes where Al Chop (Tom Towers) walks through the streets of Washington, D.C. at the end of the motion picture, just before the UFO film analysis portion, there seem to be little white-ish objects placed on the sidewalks and even near his parked car. Because they stand alone, their locations devoid of trash or anything similar, I assume they served as markers showing Towers where to walk or perhaps as objects to designate camera positions or the like. They are readily apparent to the viewer, and if they are what their presence suggests, it is puzzling that something so obvious and actually distracting from the story's flow (to me) would have been missed during filming. Of course, I could be wrong about all of this, and we'll probably never know for sure unless sharper eyes or better optical equipment than mine discover another solution.
