Pre-teens chase Moore for autographs at pic's preem

HOLLYWOOD — “Chasing Liberty” scribe David Schneiderman reveled in his pic’s bow during the Ivar after-party Wednesday, noting for a writer such festivities are “like a party thrown for the biggest nerd in high school.”

Producer Broderick Johnson, meanwhile, had a more cautious reaction. “As a financier, it’s stressful because you don’t know if there’s reason to celebrate until Friday night,” he said.

Most serene was star Mandy Moore, who was surrounded by autograph-seeking pre-teens (“How was the kiss?” was one 12-year-old boy’s question about the film). She said: “I’m not a big going-out person. Get me out of here.”

And with that Moore was out the door for a six-song surprise perf at the Knitting Factory.

Among those at the preem were Warner’s Alan Horn, Dawn Taubin, Dan Fellman and Kevin McCormick; producers David Parfitt, Andrew Kosove and Kira Davis; director Andy Cadiff; co-writer Derek Guiley; stars Mark Harmon, Matthew Goode and Jeremy Piven.
