IMO, Russell Crowe was the weakest actor in the movie. His singing voice was amateurish compared to the rest. It was like community theater when he sang.
I’ve seen Les Mis on Broadway and watched concert productions of it on TV. The role of Javert requires a professional trained singing voice.
Jackman and Hathaway were up to the task. Crowe was not, unfortunately. They didn’t need an actor of the stature of Crowe to make the movie a success. I wish they had cast someone with a good singing voice for the part. It would have been a vast improvement.
Other than that, the film was terrific.
Well, I sang in a couple of local operas: Carmen, Don Giovanni. La Traviata....
Granted, It’s not opera, but I think he listened to his coaches. And I loved his scenes.
