Weekend of April 25 – 27

Tina Fey and Amy Poehler’s comedy “Baby Mama” crawled to the top of the North American box office this weekend with $18.2 million, according to studio estimates Sunday.

Released by Universal and directed by Michael McCullers, the film stars Fey as an infertile businesswoman who hires an irresponsible sluggard (Poehler) as her surrogate.  

New entry “Harold & Kumar Escape from Guantanamo Bay” debuted in second place with $14.5 million from ticket sales at 2,510 locations. Starring John Cho and Kal Penn as two stoners mistaken for terrorists, the sequel delivered a weekend opening gross almost triple that of its predecessor “Harold & Kumar Go to White Castle.”

Last week’s box office champ “The Forbidden Kingdom” slipped to No. 3, earning $11.2 million at 3,151 theaters. The Rob Minkoff-directed action spectacle, which stars Jet Li and Jackie Chan as two warriors helping an American boy free an imprisoned king, lifted its cumulative gross to $38.2 million after a solid two-week run.

Meanwhile, Nicholas Stoller’s “Forgetting Sarah Marshall” tumbled to fourth place, collecting $11 million. Universal’s romantic comedy, which stars Jason Segel as a musician struggling to get over his girlfriend Sarah Marshall (Kristen Bell), brought its domestic total to $35 million after two weeks in release.

At No. 5, Summit Entertainment’s adventure “Nim’s Island” took home $4.5 million and reached a total haul of $38.9 million. Directed by Mark Levin and Jennifer Flackett, the film stars Abigail Breslin as a young adventurer who inhabits a secret island with her father (Gerard Butler).

Screen Gems’ teen horror flick “Prom Night” dropped to No. 6 this weekend, pulling $4.4 million from 2,821 sites. The Nelson McCormick-directed thriller, which follows a young student chased by a sadistic killer, brought its cumulative to $38 million after three weeks in release.

Following closely in seventh place was Robert Luketic’s drama “21,” which took home $4 million and lifted its domestic total to $75.7 million. Al Pacino’s thriller “88 Minutes” slipped to No. 8 with a weekend gross of $3.6 million, bringing its total haul to only $12.6 million after a weak two-week run.

Rounding out the top 10 were “Dr. Seuss’ Horton Hears a Who!” with $2.4 million, and new entry “Deception,” which despite opening at more than 2,000 theaters, only brought in $2.2 million.

Exiting the top 10 this weekend were David Ayer’s “Street Kings” with a cumulative gross of $23.6 million, and George Clooney’s screwball comedy “Leatherheads,” which finished off with a total of $29.2 million.
