The infamous scene showing Billy Duncan blowing up the roadside billboard advertising Star Wars was filmed in post-production after principal shooting on the movie had already wrapped.
When Billy first discovers the laser gun and pendant in the desert, he puts the pendant around his neck. But in the next shot when he fires the gun for the first time, he's holding the pendant in his left hand.
Roddy McDowall's name is spelled McDowell at the end.
