There have been many a Matthew McConaughey impression [1] over the years, and Anne Hathaway [2]'s ready to toss her hat in the ring. When the actress sat down with Jimmy Kimmel on Monday, she talked about what it's like to spend a lot of time with Matthew, her costar in the upcoming movie Serenity [3]. "You're with him, and suddenly you find yourself kind of leaning back," she said, affecting the actor's slower Texas drawl. She asked Jimmy to call out a topic so that she could riff as Matthew, and you can see her talk football McConaughey-style in the fun clip above.
