The Keep was one of those movies consigned to cult status; a moody rarely seen horror chiller about Nazis besieged by a demonic creature.
Directed by Michael Mann, before making hits such as Manhunter, the last of the Mohicans and Heat, it was shot in Wales, starred Ian mckellen, Gabriel Byrne and Jurgen Prochnow. Muddled as it may be, it does boast some intriguing touches. The Tangerine Dream score is eerie and atmospheric, the soft focus lighting reminiscent of a 1970s flick.
Bizarre, moody and bold. A remake wouldn't be a bad prospect.
