The British indie DIRTY FILTHY LOVE offers a quirky spin on the standard romantic-comedy formula with the tragicomic misadventures of its neurochemically-addled hero. Mark Furness (Michael Sheen) is a thirtysomething architect whose marriage and career are threatened by his increasing obsessive-compulsive disorder and Tourette’s syndrome, which include repetitive and completely involuntary activities such as stair-counting, hand-washing, and swearing. When his wife Stevie (Anastasia Griffith) files for divorce and he loses his job to a subordinate, Mark turns to his doctor for help but instead meets a kindred soul, Charlotte (Shirley Henderson), who immediately diagnoses Mark’s mental disorders and offers him therapy via her own self-help group. The film’s darkly humorous yet poignant tone is carried by Sheen’s nuanced performance and an unsentimental script co-penned by Ian Puleston-Davies, whose own experiences with OCD lend authenticity to the proceedings.

The film is based loosely around events in December 1995 that culminated in the murders of three drug dealers in Rettendon, Essex, UK. On 6th December Patrick Tate, Craig Rolfe and Tony Tucker, three drug dealers well known to the police, were lured to Workhouse Lane, Rettendon. There they were blasted to death with a shot gun while sitting in their Range Rover. They had been lured to their deaths on the pretext of a lucrative drugs deal. The three bodies were found the following morning, 7 December 1995.
