Levitt's other co-stars Tony Danza and Brie Larson were on hand for the screening, however, and took the time to sign autographs for the crowd in between posing for the cameras.
"Don Jon" is the story of Jon Martello (Gordon-Levitt), a womanizer and porn addict from New Jersey. While not much can pry him away from the allure of his computer screen, "old-fashioned" girl Barbara Sugarman (Johansson) manages to grab his attention. The pair struggle to overcome their unrealistic ideals about the opposite sex, not to mention Jon's addiction, to find true intimacy and happiness.
The film hits theaters later this year, but you can check out photos from the SXSW premiere below (and check out Moviefone's exclusive pictures from the film here).
