This weekend’s box office results proved once again the simple economic principle of supply and demand. Animated pic Cloudy with a Chance of Meatballs topped the movie charts with a strong $30 million debut, quenching the drought of kids fare in the marketplace. In contrast, not even the purported female dream team of Megan Fox and writer Diablo Cody could save Jennifer’s Body from a glut of horror movies in theaters, grossing only $6.8 million, a tad better then last weekend’s disappointing $5 million opener of Sorority Row. The performances of the other two new wide releases The Informant! and Love Happens supported the current hypothesis floating around Hollywood, that movie stars no longer matter. Not Matt Damon nor Jennifer Aniston could do much to propel their movies into box office hits. The Informant! from director Steven Soderbergh grossed an estimated $10.5 million for a second place opening while Love Happens, co-starring Aaron Eckhart, bowed in fourth place with $8.4 million. Rounding out the top five was Tyler Perry’s I Can Do Bad All By Myself. In its second weekend of release, the film starring Taraji P. Henson dropped an estimated 57% to gross another $10 million for a third place finish.

The bulk of Cloudy’s grosses came from its 3-D runs, boosting the film and the total box office up significantly from last year at this time. According to the studio, the film earned between $17.5-$18 million from the advanced technology while another $2.45 million was attributed to its 127 IMAX runs. The movie from first-time animation directors Phil Lord and Chris Miller marks Sony Pictures Animation’s highest opening gross for its animated films. Next up for the studio is Hotel Transylvania, centering on a young monster hunter who falls in love with Dracula’s daughter.

In other box office news, the limited release of  Jane Campion’s festival fave Bright Star scored decently on its 19 screens for a $190,000 opening. The film has grossed $207,000 since opening on Wednesday.
