Susan Sarandon continues to be involved in the arts, hosting a screening with The Peggy Siegal Company of the Sundance-approved documentary “Ai Weiwei: Never Sorry.” Director Alison Klayman had unfettered access to the controversial Chinese political artist. “He didn’t ask to change a single thing,” Klayman told us. “He really always saw it as an independent look at him. He’s really blown away by how big it’s gotten for sure.” Also at the screening and appearing in interviews in the film were artist Dustin Yellin, photographer Aaron Stern and designer Olivier Theyskens, who arrived with a new, shorter hairdo. Sarandon came with Goldie Hawn.
