I have a second movie I would like to find out about. When I was much younger, some time in the early 90’s, my uncle was watching a sci-fi anime set in a war zone. A man and woman had been capture and equipped with what was called a “bio-cuff” around their necks. Whenever they moved or tried to escape the cuff would tighten, strangling them.
Google searching has not helped find this movie, so I’ve never been able to find out what it was.
