Friday Box Office: Avatar Readies for Fourpeat

As predicted, Avatar piled on another top-ranking Friday at the box office, lining itself up for its fourth consecutive No. 1 finish come Sunday night. As usual, it wasn't even close; despite Avatar's 47-percent drop from last Friday -- its steepest one-week slide to date -- it still took in more than double the amount of its closest new competitor Daybreakers. Among other debuts, the beleaguered Leap Year sank into fifth place, while Sandra Bullock's cash-seeking missile The Blind Side showed its first signs of possibly running out of gas.
