After three weeks of holding tight in 5 theaters, Kathryn Bigelow's "Zero Dark Thirty" expanded to 60 theaters this weekend and showed no signs of slowing down. On Friday night the acclaimed, controversial film grossed $825,000 for a $13,750 average. That puts it on track for a weekend gross in the $2.2-$2.5 million range, which would give it a stunning average of over $40,000.
