<Li> Eddie Redmayne as Marius Pontmercy, a student revolutionary who is friends with the Thenardiers' daughter, Éponine, but falls in love with Cosette . He found director Hooper's vision "incredibly helpful". On collaborating with Hooper, Redmayne said, "He was incredibly collaborative . Certainly during the rehearsal process, we sat with Tom and the Victor Hugo book adding things ." It was Redmayne who suggested to Hooper that his character's song, "Empty Chairs at Empty Tables", should begin a cappella in order to better express Marius' guilt and pain . </Li> <Li> Helena Bonham Carter and Sacha Baron Cohen as the Thénardiers, a pair of swindling innkeepers . Hooper previously collaborated with Bonham Carter in The King's Speech, in which she portrayed Queen Elizabeth, King George VI's wife . Baron Cohen and Bonham Carter previously co-starred in the film adaptation of the musical Sweeney Todd: The Demon Barber of Fleet Street . When Baron Cohen accepted the role of Thénardier, he had to abandon Django Unchained . </Li> <Li> Samantha Barks as Éponine, the Thénardiers' daughter . Having previously played the role at the 25th Anniversary concert and in the West End production, Barks said "there was similarities in playing the role--they're the same character--but Eponine in the novel and Eponine in the musical are two kind of different girls, so to me it was the thrill of merging those two together, to get something that still had that heart and soul that we all connect to in the musical, but also the awkward, self - loathing teenager that we see in the novel, trying to merge those two together ." She found Jackman "fascinating to learn from, and I feel like that's the way it should be done". </Li> <Li> Aaron Tveit as Enjolras, the leader of Les Amis de l'ABC . Hoping to play Marius, Tveit submitted an audition tape in which he sang "Empty Chairs at Empty Tables" and "In My Life". He had never performed any role in the musical . He also said of Enjolras that "once I got more and more familiar with the material and when I read the novel, I was like,' Wow this is a really, really great role,' and I felt very much better suited for it ." Tveit said the shooting of the film was "almost as grueling as a marathon". </Li>
