Chemical Wedding

Turning his hand to screenwriting, Iron Maiden's Bruce Dickinson lives up to a heavy-metal cliché by concerning himself with Aleister Crowley, who, for the purposes of this horror melodrama, is taken to be a genuine sorcerer rather than a tedious crank. Co-written by its director, Julian Doyle, the film is set in modern-day Cambridge, where a stuttering don becomes possessed by Crowley's malign spirit, thanks to a reckless supercomputer experiment. Simon Callow plays this character as exuberantly as you would expect, but is neither scary nor - after a short while - entertaining. The same goes for the film as a whole.
