Rest in Peace Mr Kruse!
I remember seeing the movie when I was a small boy. If I recall correctly, I got to see it because my Dad was working at Shell at the time and they showed the movie to their employees. A friend and I replayed the sand dune scenes with a Dinky toy Morris Commercial artillery tractor for days on end. I think that is how I got pre-occupied with CMPs . . . . thank you, Tom!
