I'm hoping you guys can help me with this one, though I admittedly don't have much to give you. The movie was described in very short detail by a friend. Essentially the plot is that a princess(?) is taken hostage, and placed in a glass tube, to be drained of blood for some nefarious reason, and the main character goes about the movie trying to save her. Supposedly the movie is from the 80's. Any help you guys can give is greatly appreciated.
