Irvine Welsh adaptations haven’t seen much success since Danny Boyle’s Trainspotting first brought his work to the big screen — 1998’s The Acid House was disjointed at best, and 2012’s Ecstasy was essentially a poor rehash of Trainspotting (even its poster mimicked the earlier film). Released last year in the UK and earlier this year in the US, Filth hoped to fare better, employing a cast that included Jamie Bell, Jim Broadbent, Eddie Marsan, Imogen Poots, and as the manipulative, drug-addled, alcoholic, abusive Detective Sergeant Bruce Robertson, James “Young Professor X” McAvoy. The film follows Robertson’s exploits as he investigates the murder of a Japanese student, slowly descending into insanity amid severe hallucinations. It’s a dark, twisted comedy, and most critics went along with it, particularly for McAvoy’s performance, even if many found the film lived up to its title a bit too accurately. Another fairly barebones release, Filth comes with just a behind the scenes featurette and its theatrical trailer.
