Marisa Tomei, Robin Williams, Wesley Snipes, Liev Schreiber, John Turturro, James Gandolfini, Angie Harmon, Sophie Dahl, Woody Harrelson, Macaulay Culkin, Illeana Douglas, Chris Meloni, Caroline Rhea, Star Jones, Jewel, Mark Consuelos, Frederique van der Wal, Duncan Sheik, Molly Shannon, and Yoko Ono flooded the Hudson Hotel’s Library Bar, while Spacey kept his cool rackin’ em up at the pool table. HBO’s Oz star Chris Meloni arrived with his wife when The Sheet asked, “Are you looking forward to more nude scenes in upcoming episodes of Oz?” His retort: “Yes, and then some.”
