Rufus Wainwright's Tribute to Mom: Singer Rufus Wainwright had no experience producing documentaries, but it took him only a year to get one made and shown at the first Sundance London. The concert film, Sing Me the Songs That Say I Love You -- about his mother, Kate McGarrigle, who died in 2010 -- features Norah Jones, Emmylou Harris and others performing her folk songs in 2011. "We raised the money, shot it and could have dillydallied forever," Wainwright tells THR. But when Sundance London wanted it, the crew wrapped hastily. After the April 29 premiere, "My sister Martha and I sang Mom's songs -- it was emotionally devastating," he says. Wainwright's new CD, Out of the Game, includes "Candles," a song about McGarrigle. "It's hard to perform it without getting choked up," he admits. "But I go onstage with guns blazing -- I'm a bull in an emotional china shop."

Stone's Stoner Fake-Out

Oliver Stone's upcoming Universal film Savages has an all-star cast -- John Travolta, Uma Thurman, Blake Lively, Benicio Del Toro -- but the real star? Pot. When Stone and crew brought in large quantities of marijuana and plants for the film about pot growers, the studio balked. "It wasn't so much about legality," says one source on the film, "but then again, it was about legality. And about storage, insurance and perishability." When Universal demanded fake pot, production designer Tomas Voth created faux plants in all varietals. How did he make it look authentic? Says the source, "Trial and error." Stone had no comment.

Tuning In to Rita Wilson

Rita Wilson, who on May 8 is releasing a debut album titled AM/FM -- a covers collection of classics like "Will You Love Me Tomorrow" -- will perform at the Troubadour four nights earlier. But Wilson sang a preview set the weekend of April 21 at a bridal shower for friend Laurie David, who THR hears is about to get married to Bart Thorpe, the contractor who reportedly prompted her breakup with Larry David. At the home of designer Chan Luu, Wilson sang for 25 gal pals including Kelly Meyer and Arianna Huffington. "It was just time," says Wilson of her decision to record. Husband Tom Hanks helped select songs and says: "I think we went through every song she heard in the back of her parents' Barracuda."
