Actresses Whoopi Goldberg, Evan Rachel Wood and Sienna Miller helped Robert De Niro kick off the 2013 Tribeca Film Festival on Tuesday (16Apr13) by attending the annual Vanity Fair gala in New York. The bash, hosted by Vanity Fair editor Graydon Carter and festival co-founders De Niro and Jane Rosenthal, is traditionally held on the eve of the Big Apple movie event and a slew of celebrities flocked to New York's State Supreme Courthouse to celebrate. Pregnant Wood and British beauty Miller both attended the party without their respective partners, Jamie Bell and Tom Sturridge, while fellow guests included Goldberg, Mira Sorvino, Gretchen Mol, model Karolina Kurkova, director Baz Luhrmann, Jimmy Buffett, actor Christopher Walken and author Salman Rushdie. Security at the Manhattan venue was stepped up in the wake of the Boston Marathon bombing on Monday (15Apr13), but Rosenthal insisted the event had to go on. She said, "Our hearts are with everyone in Boston. We can't let terror or fear deter us from doing anything, so we're going on with our film festival and, as the President (Barack Obama) and the Mayor (Michael Bloomberg) says, we're gonna keep on doing what we do." The Tribeca Film Festival officially opened on Wednesday (17Apr13) and runs until 28 April (13).
