WHAT'S IT ABOUT? Factory worker, who's not slept in over a year, starts hallucinating and causes gory work accident.

ANY GOOD? Moody, schizoid, amnesiac mystery that's greyer and more claustrophobic than a wet weekend in Milton Keynes. But we mean that in a very good way, bizarrely enough.

BEST BITS: Christian Bale showing off his new 3-stone physique to a hooker. Side career in Mr. Muscle TV commercials awaits.

EXTRAS: Featurettes, interviews, commentaries and deleted scenes.
