Let me recommend a film to you: Heretic starring Hugh Grant, Sophie Thatcher and Chloe East (opens in the US today.) Ostensibly a horror film, it’s actually a dissection of religious faith: what we believe, why we believe it, its origins and how we might break free from it.

While there are a couple of grisly bits in it, it is actually a psychological thriller, with Grant’s character, Mr Reed, intent on breaking down the faith of two Mormon missionaries who have the misfortune to pay him a visit. Despite the hapless women being LatterDay Saints, his arguments apply to all religious belief. The film is a vehicle for this breakdown and demolition of faith. It veers into unpleasantness only in its final quarter, after taking a cynical swipe at the idea of resurrection.

I’m usually averse to horror films and only went to see this one because of the plaudits Hugh Grant’s alternately fatherly and menacing performance received from critics. He really is superb and Sophie Thatcher and Chloe East are excellent as the missionaries, sustaining a Mormon sensibility until it becomes, well, unsustainable. Scott Beck and Bryan Woods’ script is incisive and engaging (if you like your religion ruthlessly dissected and exposed.) Heretic is highly recommended.
