Russell Crowe and Hugh Jackman have been confirmed for the movie adaptation of Les Miserables.
They will be joined by The King's Speech star Helena Bonham Carter, the Press Association reports.
Crowe will play Javert, a police officer in search of Jackman's ex-convict Jean Valjean.
Producer Cameron Mackintosh told the PA: "Even though I have dreamt about making the film of Les Misérables for over 25 years, I could never have imagined that we would end up with the dream director Tom Hooper, and the dream cast of Hugh Jackman and Russell Crowe as the two great protagonists Jean Valjean and Javert.
"Not only were they born to play these roles vocally, but they thrillingly inhabit this great score."
Both have previous form when it comes to belting out tunes - Jackman has previously performed in the stage version of the Victor Hugo novel, with Crowe recently released a well-received album, The Crowe/Doyle Songbook Vol III.
Les Miserables is due for release in 2013.
