Palm Springs location
I enjoy the scene early in the movie where Frank Sutton drives to the hillside home to meet the psycho partner, Ed Asner. Below the house is the sprawling desert of 1965 with a mountain range in the distant view. Every time I watch that scene I think that the vast expanse of desert is now wall to wall subdivision, shopping malls and/or wind generators. Can anyone from Southern California confirm if that is the case?
The location house for the scientist found dead in the swimming pool is also a beautiful location. Easy to imagine taking a swim and having a drink on a warm evening under the stars with Frank Sinatra on the hi-fi system. Oh yes, a beautiful babe hovering near by.
