An ideally cast Hayden Christensen plays a wealthy young capital-investment company boss with a fatal heart condition.

Undergoing a transplant operation, he isn’t fully anaesthetised and, conscious but paralysed, he overhears a plot to murder him…

Christensen is compelling and Jessica Alba as his new wife, Terrence Howard as his surgeon best friend and Lena Olin as his domineering mother are also excellent.

The film doesn’t quite come together at the end, but it makes for smart, intriguing and involving viewing.
