WATCH: Les Miserables Cast All Sing Live - Anne Hathaway, Eddie Redmayne, Hugh Jackman, Amanda Seyfried, Russell Crowe

Tom Hooper may have his Oscar for directing The King's Speech to encourage him, but the British director was still taking on a mammoth task with the big screen adaptation of global stage hit Les Miserables.

If directing the Paris-set blockbuster wasn't enough, he thought he'd make it just a little bit more interesting, with his star cast - Hugh Jackman, Russell Crowe, Anne Hathaway, Eddie Redmayne and Amanda Seyfried, to name a few - all singing live for every take, the first time a musical film has been made in this way.

WATCH the cast in action above in our behind-the-scenes clip.

Les Miserables will be in UK cinemas on 11 January next year. Watch the first trailer below - was Hooper right to make his cast sing?
