With previews over, the curtain went up last night on Katie Holmes' Broadway debut in Arthur Miller's All My Sons. The stars gathered to see her, including Jada Pinkett Smith, Patricia Clarkson, Barbara Walters, Blythe Danner and Isabella Rossellini. Katie got plenty of support, with her and Tom's families filling the audience. The playwright's daughter, Rebecca Miller, had high praise for the Broadway newbie. "The thing about Katie Holmes is that she's so right for the part," said Rebecca.
