Two elusive legends turned heads at agency William Morris Endeavor’s Oscar party at the home of uber-agent Ari Emanuel. Morrissey, the former Smiths singer, held court with power players while Patrick Stewart chatted to admiring guests. Others at the exclusive Friday bash included Best Picture “Argo” director Ben Affleck, Emma Watson, “Les Misérables” hunk Hugh Jackman and his wife, Deborra-Lee Furness. An on-form Russell Brand worked the room, which was decorated with paintings by Retna (who was part of MoCA’s “Art in the Streets” exhibition that set attendance records in LA). Also spotted were Larry David, “Bernie” star Jack Black and Charlize Theron, looking beautiful with cropped blond hair in advance of her Oscars dance number with Channing Tatum. The stars were joined by industry powerhouse executives including DreamWorks Animation head Jeffrey Katzenberg, Paramount’s Brad Grey, CBS’s Les Moonves and Viacom’s Philippe Dauman.
