And the Box Office Champion this week is..

Sony's 3D animated feature " Cloudy With a Chance of Meatballs" enjoyed a balmy weekend opening, topping the rankings with an estimated $30.1 million in domestic boxoffice.

Warner Brothers' " The Informant!" -- a Matt Damon-toplined whistleblower thriller -- bowed about as expected with $10.5 million in second place amid lackluster competition. Tyler Perry's " I Can Do Bad All by Myself," from Lionsgate, dropped 57% from its week-earlier tally to register $10.1 million in third place, with a 10-day cume of $37.9 million.

Universal's romantic drama " Love Happens," starring Aaron Eckhart and Jennifer Aniston, debuted with a tepid $8.5 million in fourth. Fox Atomic's horror film " Jennifer's Body" was buried deep in fifth place, as the Megan Fox starrer disappointed with a $6.8 million bow.

Another horror film -- Summit's similarly R-rated "Sorority Row" -- dropped a relatively modest 51% in its sophomore session to register $2.5 million in ninth place, with an $8.9 million cume. Three rungs higher, second-frame holdover "9" -- an animated feature from Focus -- recorded $5.5 million on a 49% slide for a 12-day cume of $22.8 million.

Collectively, the weekend top 10 fetched $83.3 million to mark a 14% uptick from last year's comparable frame, according to Nielsen EDI.

In a limited opening, fledgling indie Apparition launched its first pic -- Jane Campion's romantic drama "Bright Star" -- in 19 locations in six cities to gross $190,343.

That represented a bright $10,018 per site, as cume reached $207,289 since a Wednesday bow in New York. "Star" will shine in a total 32 markets when it expands on Friday.

IFC Films' Juliette Binoche starrer "Paris" arrived in six theaters in New York and L.A. and grossed $46,800, or a pleasing $7,800 per venue. "Paris" broadens into 15 cities on Friday.

Elsewhere in the specialty market, Variance Films' Asian-American dramedy "White on Rice" added two screens for a total four playdates in four West Coast cities and grossed $9,200. The runs cooked up a thin $2,300 per engagement -- or a more acceptable $3,000 after excluding a site programming only early-morning showtimes -- as cume reached $20,170.

Based on a popular children's book, "Meatballs" featured about 1,828 Imax and RealD 3D screens among its 3,119 theaters. Produced for less than $100 million, the film features a voice cast including Anna Faris and Andy Samberg, and was co-directed by Christopher Miller and Phil Lord.

"The trailer on the film played extremely well," Sony distribution president Rory Bruer said. "All of the marketing materials really worked, and the movie delivers on that."

The PG-13 pic drew audiences composed 79% of family patrons, with 52% female support.

"Informant!" -- the exclamation point underscores comedic elements -- was co-financed by Participant Media. It opened to audiences evenly split between males and females, with 72% of patrons aged 30 or older.

"It performed as expected," Warners distribution topper Dan Fellman said.

As a well-reviewed adult pic, the film should have an unusually leggy run, Fellman added.

"Love" played in a relatively modest 1,898 locations. Its opening audiences were composed 78% of females, with 71% of patrons aged 30 and older.

"It was a solid result and in line with our expectations," Universal distribution president Nikki Rocco said.

Co-financed by Relativity Media, "Love" was produced for an estimated $18 million.

Produced for $16 million, "Body" attracted audiences 51% female, with 70% of patrons under age 25.

"We always want more, but it was a modestly budget project," Fox senior vp distribution Chris Aronson said.

Looking ahead, three wide openers are set for Friday. MGM gets back into the distribution game with the female-targeting musical "Fame," Overture unspools Dennis Quaid starrer "Pandorum" and Disney sends out sci-fi thriller "Surrogates," starring Bruce Willis.
