New release 21 beat the Vegas odds for a first place win at the box office (ending March 30), earning $23.7 million for Sony (vfx by Proof).
After two weeks at the top, DR. SEUSS' HORTON HEARS A WHO! (Fox) dropped to number two, earning $17.4M for a gross of more than $117M.
Spoof flick SUPERHERO MOVIE came in third with $9.5M, giving MGM/Weinstein probably enough to keep the franchise going for years to come. Animal Makers and Patrick Tatopoulos Design did vfx for the film.
Fourth place goes to Lionsgate's TYLER PERRY'S MEET THE BROWNS, slipping from second place last week with $7.8M.
Also creeping down the charts was Owen Wilson's bodyguard comedy DRILLBIT TAYLOR, earning $5.8M for Paramount and good enough for fifth place.
Scary photography film SHUTTER (Fox, vfx by BIG-X and Pixel Magic) brought in $5.3M for a total two-week gross of just more than $19M.
10,000 B.C. (Warner Bros, vfx by MPC and Double Negative) is close to making its money back with $84.9M total gross and seventh place this week with $4.9M.
Films about the Iraq war continue to prove mostly unpopular, as Paramount's STOP-LOSS debuted in eighth place with $4.5M, despite positive reviews.
Ninth place went to COLLEGE ROAD TRIP (Disney, vfx by Digital Pictures Iloura, Furious FX and RotoFactory) with $3.5M.
Rounding out the top ten is Lionsgate's THE BANK JOB (vfx by Digital Pictures Iloura) with $2.8M.
Animated Oscar-nominee PERSEPOLIS (Summit Entertainment) earned $30,500 on 39 screens and documentary CHICAGO 10 (Roadside Attractions) made $8.120.
