Casino came to the Big Apple as Calvin Klein hosted a special screening of the movie, “21.” The film is based on a true story and stars Kate Bosworth and Jim Sturgess as MIT students who put their math skills to work at the Vegas blackjack tables. Bosworth was on hand for the screening, as she’s also doing double duty as the frontwoman for Calvin Klein’s latest campaign.

Although there were games to be played, the stars of the movie left the card playing to their characters, though, and opted instead to pass time with other A-list friends, like Mary Kate Olsen, Clive Owen, Mamie Gummer and Elle Macpherson.

Meanwhile, the B-52’s Fred Schneider headed straight for the tables. He told WWD, “I’m off to Vegas next week so I guess I better start practicing.”
