The stars of The Dark Knight Rises gathered in London this evening for their UK premiere. Anne Hathaway wore a Gucci gown with an intricate neckline to pose on the carpet with costars Tom Hardy and Christian Bale. Marion Cotillard, one of Dior's spokeswomen, showed her brand loyalty in an ensemble from the Christian Dior Couture collection designer Raf Simons sent down the runway just two weeks ago. Both Anne and Marion changed up their looks since Monday's NYC debut of The Dark Knight Rises. For the Big Apple screening, Anne wore white Prabal Gurung and Marion also donned a light, poufy Dior creation. The final installment of Christopher Nolan's Batman trilogy is out in both the US and the UK Friday, and so far, critics are nearly uniform in their praise for the finished product.
