Based on the original Broadway production, here are a few:
> Several scenes include incidental spoken dialogue to advance or elaborate on plot points (such as Valjean asking Fantine where to find her daughter), whereas the musical is completely sung throughout.
> One song - "Suddenly" - is added.
> One song - "Dog Eat Dog", which Monsieur Thénardier sings in the Paris sewers - is replaced with a spoken dialogue between him and Valjean, but the scene of him looting dead bodies remains.
> Another song - "Turning", sung by the women of Paris after the barricade falls - is truncated.
> Fantine is shown selling both her hair and teeth, which is part of the novel. The stage version only included the hair.
> Fantine's signature song, "I Dreamed a Dream", is moved after "Lovely Ladies" (on stage, her despair leads to her descent; by moving the song, her descent leads to her despair).
> The scene where Marius threatens to blow up the barricade during the first attack is not present in the play, but in the book.
> In the movie, Valjean sees Javert during "At the End of the Day" and speaks with him shortly after in an extra scene before "The Runaway Cart". In the play they don't meet until Valjean interferes during Fantine's arrest , which is followed by "The Runaway Cart".
> A scene is added, in which Javert remorsefully urges Valjean - now the respected mayor - to press charges for being falsely accused by him. This scene is present within the book.
> Valjean and Cosette's escape to the convent, which is part of the book, is added.
> "Stars" is moved from after "The Robbery," in the stage version, to after Javert chases Valjean and Cosette through the streets of Paris following Valjean getting Cosette from the Thénardiers in the movie. This is closer to the novel, where Javert is on Valjean tail after he gets Cosette but does not see Valjean again, not suspecting him at the Robbery, until Javert is imprisoned at the barricade.
> On stage, Marius is present when Eponine stops her father from raiding Valjean's house.
> In the movie Eponine withholds the letter from Cossette for Marius until her death, which does not happen in the stage version but does in the novel.
> As in the book, it is Gavroche, not Eponine, who delivers a message to Valjean, which figures in the finale.
> Marius' grandfather, a character in the novel, is included here.
> Eponine's song, "On My Own", precedes the ensemble's "One Day More" in the movie. On stage, the latter ends Act One and the former opens Act Two.
> General Lamarque's funeral is shown, and with it, the song "Do You Hear the People Sing?" is moved after "One Day More". Thus, "Do You Hear the People Sing?" is introduced as very much the 'anthem' of the revolution right from the get-go, and appears more often than in the musical.
> Marius is portrayed as being more active in the revolutionary movement and more is shown of the preparations and early stages of the revolution.
> Eponine initially hides a message from Cosette to Marius but makes up for it by later saving his life, which is faithful to the book (but not how it happens on stage).
> In the play, Enjolras and his lieutenants die on the barricade, not in the tavern.
> Marius pays the Thénardiers' blackmail in the stage version, wheras in the film he refuses.
> The song "Beggars at the Feast" is shortened. On stage, the Thénardiers are able to enter the wedding ball and make comments about the guests, before trying to convince Marius that they knew him from a previous high society event, whereas in the film, Marius recognises them immediately and has them removed as soon as possible.
> In the play Eponine is present alongside Fantine when Valjean dies. Since Valjean never meets Eponine in the film, it makes some sense that she wouldn't be confronting him directly (though she is visible amongst the crowd at the end). Valjean also does not encounter the bishop in the stage version, as happens in the film. The presence of the bishop at Valjean's death is alluded to in the novel form.
