Pink Floyd's song "Hey You" is featured prominently in Noah Baumbach's "The Squid and the Whale," so a perfect excuse to invite former Pink Floyd bandmember Roger Waters (left) to the party for the film, held Monday night at the American Museum of Natural History. Many party attendees were hoping to sneak a chat with the music legend, and some even sat down for some pretty lengthy chats with Waters, who seemed very casual about the whole thing. At one point, Samuel Goldwyn Films head, Samuel Goldwyn, Jr. (middle) happened by along with the company's acquisitions exec, Peter Goldwyn, so we orchestrated this "impromptu" photo.
