Jonathan Gold will next be chewing up scenery on the bigscreen, as the famed Los Angeles food critic is the subject of a new documentary with “No Impact Man” director Laura Gabbert helming.Gold became the first and only food critic to win a Pulitzer Prize in 2007. After writing for Gourmet magazine and the L.A. Weekly for several years, he moved to the Los Angeles Times early this year. Production is under way on the untitled project, which explores Gold’s quests to discover offbeat eateries in Los Angeles, has received seed funding from investor and consultant Jamie Wolf. Producers are Holly Becker (“Me and You and Everyone We Know”) and Braxton Pope (“The Canyons”). “I’ve known Jonathan for many years, since we were both much younger, and the paradox of his becoming so well known and revered in the pursuit of such an idiosyncratic, personal and obscure interest has fascinated me as it’s evolved,” Wolf said. “He seems like the ideal guide to the extraordinary multi-facetedness of this indefinable city.” Becker and Pope teamed on “The Source,” which premiered in March at SXSW and will be distributed by Drag City and Gravitas Entertainment.
