While the singing in Les Mis has been criticised as being 'rough', Anne Hathaway's overall performance - much like the overall film - has been lauded. Following a fantastic performance at the box office, Hathaway had admitted to being inspired by Susan Boyle's performance of 'I Dreamed A Dream'

Boyle sung the song for her Britain's got Talent audition, and Hathaway - as Fantine in the film - belts it out. The actress told OK! Magazine, via Gigwise, "I think she's adorable, and her story was so heart-warming. Before I knew I was going to play Fantine, I'd watched that clip (of Britain's Got Talent), when I was having a low day, and it just made me feel so wonderful. She added that, "The thing about it was of course her, but the thing that's also fun is to watch Simon Cowell's mind racing, as a producer and an adding machine! I just loved that clip!" Being littered with great songs, it seems difficult to pick one out, but for Hathaway, I Dreamed A Dream' holds a special place. "It was really exciting to take this iconic song, which is so beloved, and find a way to put it through the prism of film - and that meant having to go very, very, very deep inside myself to some uncomfortable places," she said. "But that's what we do, and those are the jobs that you remember and those are the ones that make you grow."

American Idol star Adam Lambert recently criticised the film, tweeting, "Les Mis: Visually impressive w great Emotional performances. But the score suffered massively with great actors PRETENDING to be singers."
