I held off buying these for a while until they suddenly started going out of stock everywhere, spent ages tracking down 'Night of the Werewolf', must have had it on order from four different retailers before a copy finally shipped, from some small Canadian online store if I remember. Never had a chance to pick up the BR disc, but the SD has a more than adequate print.
As for the film, I really enjoyed it - although the storyline is based on 'Werewolf Shadow' it is different enough to be interesting and visually the film is a real gothic treat - my full review
Night of the Werewolf (plus check out my recently finished 3000 word Paul Naschy bio linked from that page).
