There's actually a lot of positive things to be said about the horror genre's particular fondness for re-using and warping of classic tropes and set-ups. While some will cry stagnation, any horror fan worth their salt will let you know there's as much wonder to be found in making familiar territory as there is in breaking new ground. It's always interesting to see how new filmmakers revive old ideas or when a movie becomes so prevalent its conceit or visual language enters the cinematic lexicon.
"The Shuttered Room" is a 1967 British psychological horror movie ostensibly based on an HP Lovecraft story. It's about a couple, with a wide age gap, who move back to the lady's childhood home on a remote island to visit the old mill she's due to inherit. The locals however, do not intend to make her feel welcome. Aside from Oliver Reed, who instantly needs to do the mad nasty with youthful wife Susannah.
Oh and there's a monster in the attic. But, y'know, whatever.
