Kate Bosworth and Alexander Skarsgard Pictures at Straw Dogs Premiere

The cast of Straw Dogs gathered at NYC's Tribeca Grand Hotel last night for their big US premiere. James Marsden and Kate Bosworth shared a moment on the carpet together while their costar and her ex, Alexander Skarsgard, posed solo. She was decked out for the event in an embellished Antonio Berardi dress. Kate and new boyfriend Michael Polish have been inseparable lately, but it doesn't seem as though he accompanied her on the trip to the Big Apple. Even though Kate and Alex avoided each other, he still had kind words to say about her work in the movie. Alex spoke to reporters about Kate, saying "She was great. . . . She's a total pro."
