On an afternoon in early August, Rebel Wilson was standing on a raised platform in a changing room on the Warner Bros. lot in Los Angeles trying to explain why she didn’t want to look pretty. A rack of clothes was being offered for Wilson to wear on "Super Fun Night," a situation comedy that will air on ABC on Wednesdays at 9:30 p.m., about three girlfriends who attempt to overcome their social awkwardness by going out every Friday evening.
Judy Gellman, the show’s costume designer, had assembled an array of jewel-toned, conventionally attractive ensembles for Wilson to try on and approve. Wilson, who not only stars on the show but wrote the pilot, which was based on events from her own youth in Australia, was notably quiet about the choices. “I don’t know,” she said softly, inspecting each garment. “These look like something I would wear, and that isn’t right.”
