Russell Crowe hopes that the music from upcoming movie Les Misrables will "touch hearts".

The actor discussed the film adaptation of the hugely successful musical with his followers on Twitter and revealed details about the soundtrack.

The star is portraying Inspector Javert in the latest version of the Victor Hugo classic.

When asked whether the accompanying score would be recorded separately or using material from the film, Russell was seemingly confused but said he hoped fans would like the selection.

"The soundtrack of the film is the soundtrack of the film... I don't understand your question," he wrote on his Twitter profile. "I hope there's a tune or two in that lot that touches your heart. All the best (sic)"

Russell also revealed that the cast in the musical movie would be singing live in every scene during shooting.

The Gladiator hunk said that unlike most films, the Les Misrables tracks would be recorded on set.

"Pretty much every filmed musical ever done is mimed to a pre-recorded soundtrack... in fact i don't know of one not," he clarified to a fan. "on this, as has been widely reported, we will sing every take and the orchestration will be recorded afterwards, radical really (sic)"

Les Misrables boasts a star-studded cast with names such as Hugh Jackman, Anne Hathaway, Helena Bonham Carter, Amanda Seyfried and Sacha Baron Cohen also appearing.
