George Clooney stepped out with his The Ides of March costars in Venice today. Marisa Tomei, Evan Rachel Wood, Paul Giamatti, and Philip Seymour Hoffman posed together at the movie's premiere, which was the first of the Venice Film Festival. The film's other leading man, Ryan Gosling, apparently didn't make the trip overseas since he's busy working on The Place Beyond the Pines and promoting Drive. George's pals Rande Gerber and Cindy Crawford, in Robert Cavalli, came out to show their support, though, as did Diane Kruger, who sparkled in an Elie Saab gown. The Ides of March cast was up early for a photocall to promote the project this morning, though they stepped up their looks for this evening's event with Marisa donning a yellow number by Marios Schwab and Evan debuting a dramatic white dress. The glamorous fun is just beginning since Kate Winslet, Gwyneth Paltrow, and Selma Blair are a few of the stars expected to make appearances at the festival.
