Ig Perrish (Radcliffe) is the prime suspect in the violent rape and murder of his girlfriend Merrin (Temple). Hungover from a night of drinking, Ig awakens to find horns growing from his head. He soon realises that their power drives people to confess their sins and give in to their most selfish and unspeakable impulses – an effective tool in his quest to discover the true circumstances of his late girlfriend’s tragedy and to exact revenge on her killer.
When Ig Perrish (Daniel Radcliffe) wakes with a splitting headache, it’s more than just the mother of all hangovers. He has satanic protuberances growing out of his temples. These newly grown horns prove unusually useful in Ig’s mission to prove he did not, as accused, kill his own girlfriend, as they force anyone nearby to confess their darkest secrets. Keith Bunin’s script sticks slavishly to Joe Hill’s source novel, which doesn’t work without the book’s inner monologue. It makes for a confused, uninvolving story, not helped by Aja’s inconsistent tone.
Long-shelved, the final product never lives up to the promise of its contemporary-Grimm-brothers conceit.
