Teen pregnancy rules! At least, at the indie box office it does, as Junoexpanded to 1,925 theaters, maintained a healthy per-screen average ($8,428, the second highest among wide releases) and swept easily into third place in the overall standings, according to estimates compiled by Box Office Mojo. Grossing more than $16 million over the weekend, with a cumulative total of $52 million, Juno has benefited from an extensive marketing campaign by Fox Searchlight, very strong critical reaction, and, presumably, excellent word of mouth.

The highest per-screen average among wide releases belonged to Atonement. Expanding to 583 screens, the period drama from Focus Features drew $8,789 per engagement. Atonement is in its fifth week of release, as is Juno, and though the period drama continues to be outpaced by the teen comedy, it's performed very well overall.

Among more limited specialty releases, There Will Be Blood was the star, earning $26,215 per screen at 51 locations, which should please distributor Paramount Vantage. The film is due to expand into 125 screens on Friday. I think it's a tremendous, engaging film, but it's a demanding experience, which usually doesn't translate into big box office.

Even without any known stars (and in Spanish!), The Orphanage did quite nicely, pulling in $7,590 per screen at 66 theaters for Picturehouse. It will move onto 500 screens later this week, which will give me a chance to see it; I'd love to see more foreign-language genre pictures get this kind of release.

Animated French-language Persepolis expanded to five more screens and made $11,428 per location for distrib Sony Pictures Classics, which bodes well as it continues a platform release. The Diving Bell and the Butterfly appears to be benefiting from all the critical hosannas it has received, reaping $6,000 per screen in its sixth week of release by Miramax.
