The film is a stodgy snooze, and Theron, who is about as expressive here as a porcelain doll, lacks all believability--she's followed her best performance (in Monster) with her worst.

The film feels more at home with sex than war, like a romance novel where the swinging lovers find their passions stirred by bombs exploding in the distance. Their three-way dalliances are so frivolous and silly that once the action turns dark, Duigan and his cast leave audiences unprepared for the emotional fallout.
Stuart Townsend, Theron's reallife boyfriend, may have inner fires as an actor that have yet to be revealed, but in Head in the Clouds he's a somber puppy who looks as if Theron could eat him alive. I wish she had.
