A movie I recollect seeing way back in the 70’s revolved around a missing child. When the child was finally found, asleep in a barn I think, someone was yelling “don’t touch her!” It turned out to be a life like doll of some sort. Someone either stuck it with a pitch fork or broke the head open. The actual fate of the child remained unknown.

I lucked out in my other great unknown movie turning up on TCM a few years back.

All I was able to recall about this movie for decades was people in a castle being turned into statues by a mad scientist fellow. If I had recalled Christopher Lee was in the movie, I would have found it a lot sooner.
