Cool!
So does the movie have actual spoken dialogue, instead of it all being sung through?
It has some spoken dialogue, but it has the sung-through dialogue as well, and none of the songs from the show have been cut, although some, like "Turning", have been shortened. Others have some new lyrics, since the movie setting is different than on stage, and others have been rearranged - like "Lovely Ladies" now comes before "I Dreamed a Dream" (which you can tell from the trailer, since her hair is already cut when she's singing it).
There's also a new song called "Suddenly", that Valjean sings after taking Cosette from the Thenardiers, about suddenly becoming a father. There's a lyric change there that I love too: in the show, Cosette asked Valjean "Will there be children and castles to see?", in the script, she sings "Will you be just like a Papa to me?"
There a lot more between Valjean and Javert - and a fight! There were some new lyrics there too. Gavroche has some new lyrics during "Look Down" too. He's leading a group of kids through the streets (I believe they're the running kids you see in the trailer), and he singing his parts of the song to them. He also emerges out of the Elephant of the Bastille, which we saw from those set pics a few months ago.
They've also incorporated a bunch of stuff from the original Victor Hugo novel into the movie now. I've put those in white text below so you can highlight them to see (didn't want to spoil it) -but this is all from the book, and now part of the movie:
-Fantine sells her teeth as well as her locket and hair
-Gavroche and Eponine are brother and sister
-Marius' grandfather is in the movie
-Valjean hides with Cosette in a convent after taking her from the Thernardiers, and the groundskeeper who hides them from Javert is the man Valjean rescued from the runaway cart
-Gavroche is the one who takes the letter to Valjean about Marius being at the barricade
But it's completely intact from the stage version, nothing has been cut or tampered with. I heard the screenings have run nearly 3 hours, so it's going to be epic.
