Then it really is Old Scratch knocking at the door. Something of the forgotten John Carpenter movie, Prince of Darkness shows both the good and bad side of the supremely talented director. The story is a beaut, a bit skew-whiff, but unmistakably Carpenter territory as Satan exists in some sort of parallel universe. How he manifests himself is narratively a bit tricky, but still it makes for good horror, especially as the old religious angle finds Carpenter - in the guise of Donald Pleasence - chortling away to himself in a way that Old Nick has been prone to do. Cue bugs, green goo, zombies and a centuries old sect determined to keep Satan out of our world. The scares are many, atmosphere bubbling away (in time with another of Carpenter's pulse beat synth musical scores), while the finale has a genuine surprise up its sleeve. Unfortunately the cast are playing second fiddle to the supernatural strengths, working from a script that doesn't sit at one with the screenplay, rendering the characters as uninvolving fodder. Yet be that as it may, it's still a film of delights, enough in fact to make it a top end entry on Carpenter's CV. 7/10

When an elderly priest passes away, one of his colleague discovers a mysterious green liquid hidden in a cylinder deep beneath a long-abandoned church. Rather misguidedly, as it turns out, he invites a group of enthusiastic students to come and investigate it's properties. Big mistake! It was hidden deep in the bowels of this crypt for a very good reason, and once they release it they discover that the Satanic horror they face might just be the tip of the iceberg! Donald Pleasence is strong here as the priest who realises, all too late in the day, that they are facing a terror that could jeopardise the very future of humanity... Christianity at any rate! Can he galvanise his now panic-stricken helpers to reverse the effects of the deadly gloop before they all become zombified servants of evil? The dialogue maybe isn't so hot, especially as hysteria begins to set in amongst the petrified, but the pace is great and the effects have held up remarkably well as this solid and quite menacing story builds to a genuinely exciting conclusion. The supporting cast deliver well, too and John Carpenter and Alan Howarth manage a score that adds quite a bit of peril to the accruing sense of danger the former creates throughout this rather superior drama. It's short, taut, and well worth a watch.
