Matt Damon credits his baby with helping him achieve the worn-out look of a man on the run in THE BOURNE ULTIMATUM - the little girl kept him awake at night as he was shooting the sequel. Damon's wife Luciana gave birth to daughter Isabella in June 2006, just before the actor began filming The Bourne Ultimatum. He says, "I look so exhausted... Even if I tried to have a methodical sleep-deprivation look in the film, it wouldn't be as authentic as me being up all night with a crying baby at home."
