Actor James McAvoy (X-Men: First Class, Trance) and director Jon S Baird (Cass) discuss their latest film. Adapted from Irvine Welsh's original novel, Filth sees Bruce Robertson (McAvoy), a bigoted and corrupt policeman with a crippling drug habit, manipulate his colleagues in a bid to secure a promotion. With the web of deceit beyond his control and his past catching up with him, he struggles to keep his grip on reality long enough to disentangle himself from the filth. Moderated by Edith Bowman at the Apple Store Regent Street, London.
