The best part of the movie is knowing it was filmed in Dallas in 1966. Actually, the exterior shots of the scientist's headquarters were filmed at my childhood home in Dallas -- it was quite contemporary for its time. One Sunday morning the producers knocked on the door wanting to use our home, we consented, and 2 days of muddy footprints and dirty coffee mugs later, the actors and filmmakers left. We enjoy watching the familiar scenes shot at White Rock Creek and Casa Linda Shopping Center -- particularly the mass chaos scenes of a running mob. Not a great plot and especially bad props -- Zontar looks like a black plastic bag stuck on a wire that flaps in the air.
