Last time I checked I heard MGM were holding the rights....meaning it'll most likely remain unreleased in some vault.....
I remember this very well, as it was one of my first rental VHS tapes from the very much restricted "adults" section of a Munich video store.
Of course, even the litttle gore present was cut in the German reelase....but it's a very atmospheric and entertaining little film, which I'd be more than happy to pick up on DVD...until then my VHS copy from '89 will have to do...IF the tape still palys....
Plus: the original VHS cover artwork was very cool!
