Johnny Vik (also known as The Hunted) is a 1977 movie about a military veteran who has post-war issues and gets into trouble with the local police after urinating in public. Apparently based on a true story, it is very similar to the "First Blood" Rambo movie starring Sylvester Stallone with less violence.
Filming was done in Custer and around the southern Black Hills. If you are familiar with those areas, you will surely recognize many locations. I was pleasantly surprised to identify the "old gym" in the old Custer High School where I spent many hours working on play productions, disc jockeying school dances and attending pep rallies. There's no telling how many times I've walked up and down the stairs outside the gym.
I've just been informed that a blu-ray version of the film may be coming soon and there is also work being done on a possible screening in Custer this summer.
