Big budget Iron Man racking up big box office? Not a shock. The latest from Harmony Korine (Gummo, Julian Donkey-Boy) topping the indie box office chart? That's a surprise. Mister Lonely (IFC Films) only opened at one theater in Manhattan, but it took in $19,100 for the highest per-screen average among indies this weekend, according to estimates compiled by Box Office Mojo. Diego Luna plays a Michael Jackson impersonator; Samantha Morton, Denis Levant and filmmaker Werner Herzog also star. Our own Jeffrey M. Anderson wrote: "Though Mister Lonely seems sweeter and more mainstream than Korine's other films, it still has that sense of randomness, of pathetic luck and habit and wisdom all combining to make up a life, or a collision of lives."

David Mamet's Redbelt (Sony Classics) pulled in $11,433 per screen at six locations. Chiwitel Ejiofor stars as the honorable owner of a Jiu-jitsu studio who is drawn into the world of "pay-per-view mixed martial arts," as Cinematical's James Rocchi described it. He did not feel the film matched the writer/director's best work; "still, even minor Mamet can be a source of major satisfaction, especially with an actor as compelling as Ejiofor in the lead."

Son of Rambow (Paramount Vantage) averaged $10,500 each at five theaters. Garth Jennings' delightful kids' adventure follows two boys as they create their own action movie epic featuring John Rambo. James Rocchi called it "a brilliant celebration of the exuberance and thrill of bad storytelling, of making art, of having dreams."

Jeremy Podeswa's Fugitive Pieces (Samuel Goldwyn) opened in 30 theaters but did not fare so well, grossing an estimated $3,600 per screen. The film, which opened the Toronto film festival last fall, received mixed reviews. Robert Koehler of Variety wrote: "Account of a Jewish boy's survival during the Holocaust, care of a doting Greek archaeologist, and his subsequent troubled adulthood becomes a belabored pattern of flashbacks and flash-forwards onscreen."

Holdovers The Visitor (Overture) and Young @ Heart (Fox Searchlight) continued to draw audiences, with the former taking in $5,100 per screen at 130 theaters and the latter scoring $2,727 per screen in 130 theaters. Both films are in the fourth week of their release. Leonard Klady of Movie City News commented: "Neither is likely to set records even within the limited realm but both are bearing up against the increasingly competitive and sated rarefied adult crowd."
