Visible crew/equipment: During the scene in the gas station with snakes, as Dennis Weaver is wiping the tarantula from his leg, look at the shadow of the old woman behind him. There appears to be a moving crew member shadow next to hers. It cannot be a tank as she wasn't standing next to one either in the shot before or after.
Visible crew/equipment: At the gas station, just before the water is sprayed on the windscreen and the attendant first appears, if you look closely at the top right hand corner of the screen you can see a reflection (albeit for a split second) of a hand giving the cue for the action to begin. Was this Steven Spielberg's hand?
