Time Out says
Why did Clay suspect nothing when, seconds after his spontaneous marriage to the beautiful Sam (Jessica Alba), the hospital phoned with news of a replacement heart? Perhaps he was preoccupied with the reaction of his over-protective mother, Lilith (Lena Olin), to his secret nuptials. Sam and Lilith also clash over the mother’s attempts to replace Clay’s surgeon friend, Dr Jack Harper (Terrence Howard), with her own man.
Unfortunately, it’s hard to tell the difference between Christensen’s conscious and anaesthetised states, even when Clay’s ‘out of body’ self starts padding about in his hospital pyjamas, his monotonous voice-over commenting on the unfolding drama. The medical madness spirals off the chart, the credibility factor flat-lines, and the laughing gas kicks in.
