“Patti Smith is such a goddess. I could never talk to her,” Parker Posey confided at a small cocktail reception for the legendary rock ’n’ roll poet last week in the outdoor sculpture garden at the Museum of Modern Art. At said moment, Smith came lunging in for Posey, lavishing praise on the indie queen for her hilarious roles in Christopher Guest movies. It couldn’t have been a better-scripted scene if Guest wrote it himself. Luckily, Posey overcame her goddess-shyness and lit right up in Smith’s presence. The occasion was a screening of Patti Smith: Dream of Life, a poignant biopic from fashion photographer Stephen Sebring that hit theaters this week, after eleven years of filming.
