Kate Winslet hit the Carnage red carpet at the Venice Film Festival in a high-volume ponytail and neutral Victoria Beckham dress today. The actress attended the premiere without Louis Dowler by her side, but her costars Christoph Waltz and John C. Reilly each posed for pictures with their significant others at the debut. Among the stars in attendance was Bar Refaeli, who wore a sexy pantsuit to the event. Kate was also on hand this morning for a press conference on the big-screen adaptation of the critically acclaimed play God of Carnage. She headed to Italy following a Caribbean vacation with Louis and her children, Joe and Mia, just last week. The trip ended in near disaster when a fire broke out at the home of Richard Branson, who was hosting the foursome, but Kate saved the day by helping evacuate her loved ones and Richard's elderly mother from the house.
