Figures in a Landscape

I saw this movie for the first and last time on Dutch television in the late 70's / early 80's. I was 9 or 10 years old at that time. I remember it gave me the creeps. Especially the helicopter... that could show up at any time. This film has been in my head for a long time (not remembering the title) Since I know the title (recently) i can't wait to see the movie again but unfortunately this films isn''t available on tape or DVD. I wonder what happened to it and i would like to ask anyone involved in making this film to blow the dust from the original print and release it very soon. Then I can judge the film again and maybe come to the conclusion that it is a terrible movie after all ;-)
