Interesting article from the LA Times on the singing in Les Miserables.

>>Musical director Stephen Brooker, who also supervises the London stage show, said the cast went through extensive preparation for the film, including months of work with voice coaches and nine weeks of rehearsal. The actors brought their own vocal qualities to the roles.
As the noble ex-convict and protagonist Jean Valjean, Jackman's sound is "very muscular," Brooker said, and reflective of his extensive musical theater experience. "It's pingy at the top end, it's got energy."
Crowe, who plays Valjean's nemesis, the dogged Inspector Javert, has a background in rock music and an edgier sound, "a dark baritone," Brooker said. Hathaway, a trained singer whose mother once played Fantine in a national tour, conveys "a real sense of fragility."
A major concern regarding the live approach was ensuring that the actors stayed in singing shape. Brooker said he did his best to monitor the cast's vocal health and work load, though he recalled some "brilliant, crazy nights," such as when "Hugh Jackman was up to his ears in mud in an estuary in Kent, still singing at 2 o'clock in the morning."
Jackman survived the ordeal, voice intact. In the end, Hooper said, none of the obstacles proved insurmountable, and the results were worth the challenge.
"Singing unlocks something in actors that's different," he said. "I think I can safely say that you'll see something different from all of them that you've never seen on film before."<<<
