Don't Go Into The Attic (2003) James Shanks.

The legendarily stentorian actor Brian Blessed and the no less charismatic Julie T. Wallis provide much-needed gravitas to mostly tepid low budget British supernatural shocker 'Don't Go into the Attic'. Not long after a bland, quarrelsome young couple move into a rustic Cornish farmhouse, the local legend of Dagon becomes disturbingly manifest, and apostate cleric (Brian Blessed) must do mortal battle with this ancient evil! Anything with Brian Blessed is worth a shout, and while Don't Go in The Attic is frequently hampered by a conspicuous lack of budget, the attractive gothic locale is sinisterly steeped in Folk horror atmospherics, and the Blessed-fuelled climax proved zesty enough. Not the most credible example of Lovecraftian horror, but a valiant effort nonetheless, with Blessed's enjoyably noisome theatricality diverting attention away from the pointed fact that Lord Dagon remains wholly submerged throughout! aka Devil's Harvest.
