What’s it all about? A Cambridge professor (Callow) channels the spirit of famed Edwardian occultist Aleister Crowley.

His dark powers put locals at risk, but a student (Cudden) and an inventor (Weber) are on his trail.

What’s good? This is one bonkers movie, but it’s quite entertaining if you’re into paranormal horrors. Simon Callow is gloriously over the top as the hedonistic occultist.

What’s bad? Aside from Callow, the actors are ropey, and the plot gets very silly.

OK! verdict: It’s OK if you take it as a tongue-in-cheek B-movie
