So, here'e my take on it.
Valjean (Jackman): just amazing. Jackman has range, can hold a note, and can act at the same time as singing. I don't know his background but there must be some serious broadway there. Who am I: 24601.
Monseigneur Sumthing: This is the priest who Valjean stays with when he cannot find work. Gives candlesticks to Valjean, and buys his soul for God. This guy looked and played the part perfectly. This scene is the pivitol inflection point in the movie. "Another story must begin"!
Fantine (Hathaway): great acting, a bit over the top but consistent with the stage production, excellent singing, very nice at the end of movie (with old Valjean).
Cossette - Young (?): excellent little actress, great little voice.
Cossette - Adult (?): excellent acress, great pixie-voice with appealing vibrato; plays great with Valjean and Marius
Marius (?): This guy can sing. Looks more irish than french, but played the part well.
Gavroche (sp?): This kid was dynomite. Hard to understand in his first appearances, but played his final scene with touching perfection.
Javert (Crowe): Turd. Acted well enough, but man he just can't sing. Ruined many of the signature songs in the movie. The confrontation scene with Valjean, the "fall" at the bridge, etc. If the rest of the cast wasn't so, so strong, he could have sank this movie.
Who'd I miss?
