Visible crew/equipment: When the aliens blast off at the end of the film, the bright light causes the shadows of the actors and vehicles, etc, to appear on the painted backdrop of desert and sky.
Visible crew/equipment: In the beginning of the movie (about 10 mins. in) Steve McQueen and Aneta Corsaut are driving along and think they hit an old man on the road. They stop the car and get out. There is a shot of the rear right panel of the car, two sets of "lights" are visible reflecting off the car. One single light and 4 lights in a square shape to the right of it. They help the man into their car and there is another side shot of the car and the lights are now 3 sets of 2 lights. They're in the middle of nowhere, at night, along a country road. It looks like "light trees" used to illuminate a scene at night.
