Bale shows that he's one of the most dedicated actors of all-time.

Rating: 9/10 (26 February 2010)

Bale shows his determination at being a method-actor, in this delusional thriller by Brad Anderson, by losing a record-breaking sixty-three pounds (Bale wanted to lose more) in order to render the appearance of a man who hasn't slept in over a year. Trevor Reznik (Bale) is an industrial working insomniac whose grip on reality is slowly deteriorating and struggles to find answers to such mysterious events that begin to unravel in his everyday life: hangman post-it notes on his refrigerator, a new coworker named Ivan (Sharian) that seems to bring doubt every time he appears in Trevor's life, and a waitress (Sánchez-Gijón) who has befriended Trevor and also has a strikingly familiar relationship with her son Nicholas (Moore) that Trevor had with his mother. An overall original, interesting and thrilling film; with Anderson creating an uneasy mood of paranoia and distrust. The film tends to linger for a little while after it has made its point.
***½ (out of four)
