Madonna and Kate Winslet lent their star power to the Venice Film Festival this morning. Kate was on hand for a photo call on behalf of her upcoming film Carnage, a Roman Polanski-directed version of the hit play Gods of Carnage. Joining Kate were her costars John C. Reilly and Christoph Waltz. Kate, whose recent attempt at a vacation on Richard Branson's Necker Island was disrupted by a devastating fire, was nonetheless looking refreshed in a LBD and Michael Kors sandals. Madonna, meanwhile, wrapped up her fun in the South of France in order to attended a press event for her directorial project WE. She had leading ladies Abbie Cornish and Andrea Riseborough for company as they smiled for the cameras. Madonna said her talented exes were partially responsible for her venturing behind the lens. She told reporters today, "I am and was attracted to very creative people, which is why I married Sean Penn and Guy Ritchie, two very talented directors. They both encouraged me as a director and as a creative person to do what I did, and they were both very supportive."
