Michael Mann's movie starring Scott Glenn is a memorable horror movie that has the Nazi's on the run from a monster held in The Keep - a castle that sees Scott Glenn as ostensibly the good soldier fighting the evil of Nazism - the score by Tangerine Dream is for me - what makes this movie - along with Michael Mann's Thief - memorable,esepcially the climax as the clanging noises and vocals move the movie to it's apex where good takes on evil - well worth seeing - and it is no wonder this has become a cult classic and is much sought after on Ebay.
