Nolan's Following was one of the most original British films of the '90s, and this follow-up makes no compromise. It opens with reverse action: a Polaroid photo fading and sliding into the camera, a corpse returned to life, a gun pulled from the head, a bullet sucked into the barrel. The action thereafter plays forwards as usual - with Leonard Shelby (Pearce) out to track down and take revenge on whoever raped and killed his wife - save that the brief narrative chunks flash ever further backwards in time, so that we share Shelby's confused point of view. He suffers from a rare kind of memory loss whereby, while he remembers life before the murder, he's been unable since then to recall anything for more than a few minutes. Hence he's forever forced to fathom afresh everything he sees and hears. The photos he takes for future reference and words he tattoos into his flesh help, but life remains a mysterious, very risky business. This taut, ingenious thriller displays real interest in how perception and memory shape action, identity and, of course, filmic storytelling. Moreover, a plot strand featuring Stephen Tobolowsky even touches the heart. There's grade A work from all concerned, especially Pearce, but in the end this is Nolan's film. And he delivers, with a vengeance.
