Oscar winner Robin Williams made his Broadway debut on March 31 in Rajiv Joseph's new play Bengal Tiger at the Baghdad Zoo. Plenty of Williams' former co-stars and friends—including Billy Crystal and Susan Sarandon—came out to cheer him on as he roared onstage at the Richard Rodgers Theatre as the show's title animal. After a successful performance, Williams joined his castmates and first-night guests at Manhattan hotspot Espace for the show's opening night party.
