I was living in Wisconsin when I saw this movie advertised several times.
It would have to have been 74-76 at least.
All I know it was sci fi, featuring a young girl who kept screaming because people were getting zapped and turned into piles of ashes.
It scared me at the time! I remember we had an old newspaper with it in it, but, cannot remember the name!!! Is there a list somewhere online too, that has a real catalogue of movies made, everything else is only films that everyone remembers.....
