Sony’s spry ensemble blackjack flick, 21, held on to the top spot at the box office this past weekend, stiff-arming George Clooney’s period piece football comedy, Leatherheads. The former film, starring fresh, exceedingly likeable newcomer Jim Sturgess alongside Kevin Spacey and Kate Bosworth, grossed $15.1 million, and has now won a robust $46.5 million in its first two weeks of release. Clooney’s third film behind the camera pulled in an estimated $13.48 million at just under 2,770 theaters, while fellow new opener Nim’s Island finished just off that pace, with an estimated haul of $13.3 million at 3,500-plus screens. Also debuting this week was the R-rated The Ruins, which grossed around $7.8 million, good for fifth place. I think the problem there, as a friend of mine excellently pointed out, is that not enough people know the girl, Laura Ramsey, who gets naked in it.

Like it or not, Horton Hears a Who is the spring’s biggest hit; it grossed another $9.1 million, and has now raked in over $131 million domestically in total, and another $76 million and change abroad. Writer-director Craig Mazin’s Superhero Movie placed sixth for the weekend, adding $5.4 million to its coffers; it now stands at $16.8 million. Tyler Perry’s Meet the Browns finished seventh, with $3.51 million; Drillbit Taylor, starring Owen Wilson, finished eighth, with $3.49; the atrocious Shutter placed ninth, with $2.8 million; and Roland Emmerich’s 10,000 B.C. clung on to the 10th spot, with $2.7 million. The heavily marketed, effects-laden prehistoric actioner has now pulled in $89 million domestically for Warner Bros., and another $143 million internationally, proving that there apparently is a market for movies aimed at sabretooth tiger enthusiasts.
