Anne Hathaway at the Les Mis World Premiere in London

The cast of Les Misérables hit the red carpet in London for their film's world premiere today. Anne Hathaway wore a white Givenchy Couture gown while Amanda Seyfried went with a black ruffled Balenciaga look. The ladies posed with costars Hugh Jackman and Russell Crowe, as well as Eddie Redmayne, who chose a velvet Burberry suit. Sacha Baron Cohen and his wife Isla Fisher also hit the red carpet, as did photographer Mario Testino and designer Valentino, who created Anne's wedding gown. Anne, Hugh, and Amanda were together last night as well, when they attended a private screening of the movie. Their stop in the UK comes after a stint in Japan, where the trio posed for photos and promoted the project. Anne's husband, Adam Shulman, has joined her on her recent travels, and the couple showed PDA while out in London yesterday.
