Plexes were packed this weekend at the specialty box office — not with moviegoers but an overabundance of product looking to capitalize on the traffic spurred by summer tentpoles.

Summer box office historically has been cluttered with hopeful specialty counterprogrammers to more high-profile studio fare. But with so many specialty offerings to choose from, some pics are likely to get lost in the crowd.

This weekend’s slate of indie pics saw a mix of both good and — let’s be frank — not-so-good perfs.

Summit had hoped to improve on last weekend’s disappointing start for the Jodie Foster-helmed “The Beaver,” which expanded to 105 locations in its second weekend, up from 22. But the Mel Gibson starrer’s estimated outcome was hardly enthusiastic, tallying $158,000 for a per-screen average of $1,505.

Werner Herzog’s 3D docu “Cave of Forgotten Dreams,” released Stateside by IFC, did better in its expansion to 81 locations, of which 68 were 3D. Pic has crossed the $1 million mark in just three weeks of release. IFC also saw solid returns for its exclusive two-run engagement of French docu “L’amour fou,” averaging $18,000 per screen.

Then there were two aggressive limited bows (both coincidentally at 218 locations): Roadside Attractions’ dramedy “Everything Must Go” and Lionsgate’s Latino-targeted dance pic “Go For It,” via the studio’s Pantelion label.

“Everything,” toplining Will Ferrell, earned an estimated $825,100 and averaged $3,784 per screen; “Go For It,” however, earned much less, with a per-screen average of just $575, totaling a projected $125,000 for the weekend.

Also bowing was Sundance pic “Hesher,” toplining Joseph Gordon-Levitt and Natalie Portman, which grossed an estimated $126,811 million from 42 screens. That’s a per-screen average of $3,019.

Ending its fifth season of live transmissions, Gotham’s Metropolitan Opera screened Wagner’s “Die Walkure” for an estimated $2.3 million in North America. It was seen live on more than 850 screens, with an additional 550 in a total of 35 European and Latin American countries.
