George Clooney, Rupert Everett, James Gandolfini, Calvin Klein, Dermot Mulroney, Hilary Swank, Diane Sawyer, Susan Sarandon, Tim Robbins, Jerry Orbach, Steven Soderbergh and main squeeze of the main attraction, Benjamin Bratt, turned out at the Waldorf Astoria last weekend for the American Museum of the Moving Image's tribute to Oscar nominee Julia Roberts, reports PEOPLE. The star herself provided the most moving moment of the night, as Roberts singled out three people who mean the world to her: her sister, Lisa; her former agent, Elaine-Goldsmith-Thomas; and her "old man," Bratt, whom she called "my touchstone. He's the best reason to go home that I can think of." As for what others think of the radiant Roberts, 33, "I've been close personal friends of Julia for days now -- or J.Ro, as we like to call her," Clooney told the crowd. "You think of Julia as a movie star and a consummate actress and a great beauty. She's also a confidante. She's someone I can call up in the middle of the night, any time of the day or night, and she'll have her assistant call me back."
