John Singleton's revenge drama Four Brothers debuted at No. 1 at the weekend box office with $20.4 million, outpacing the Kate Hudson thriller, The Skeleton Key, which opened at No. 2 with $15.8 million. Last week's top flick, The Dukes of Hazzard, tumbled to third with $13 million a steep 58 percent drop. But the real loser of the weekend was man-slut Rob Schneider, whose Deuce Bigalow sequel landed at No. 5 with just $9.4 million. Heck, Divine Brown makes more than that in a weekend.
