Continuity mistake: Enjolras is holding a book during his protest which disappears and reappears at will.
Factual error: In the opening sequence, the convicts are located in a dry dock pulling on ropes supposedly connected to a listing ship in the distance. The convicts are standing in 2 to 3 feet of water which would indicate that the dock is "dry" and that the dock gates are closed. The ship will be unable to enter the dock under those circumstances. If the gates were open enough to allow the ship entry there would be 20 to 30 feet of water in the dock and the convicts would need to be up on the top of the dock to achieve their objective.Jaytack1
Continuity mistake: Toward the end, Thénardier is being dragged down the stairs after Marius took back the gold ring Thénardier stole off his unconscious body previously. The gold ring appears and disappears several times as Thénardier is being pulled out of the room, down the stairs, and out the door. At the end, Marius shows the gold ring to Jean Valjean as he is dying, which was last seen on Thénardier's finger as he was being pulled out the door.
Continuity mistake: In the scene early in the film, where Valjean is singing in the church (after the police brought him back to the minister for stealing the silver), he has a wound on the right hand side of his head (from being hit by the policeman's stick/truncheon). Depending on the camera angle, the size of the wound and its appearance alters- sometimes it is quite small and flat, other times raised. Also sometimes there is a trickle of blood from it and other times not.
Continuity mistake: In the scene where Valjean is captured and brought back with the silver, the officials that apprehend him take off their hats. However, a few shots later, when the Monsignor collects the silver back, the official who addressed him has his hat on.
Continuity mistake: In the scene where Eponine (Samantha Barks) sings "On My Own", towards the end of the song, her hands come into shot, they are immaculate and manicured. Immediately after the song, she goes into a building to retrieve Cosette's letter to Marius, whilst holding the letter her hands are filthy with dirt under the nails.
Visible crew/equipment: When Éponine sings "On my own" towards the end, when she whispers "I love him" you can see the shadow of the cameraman on her left cheek as he leans closer, and then disappear as the camera apparently zooms out and the cameraman backs away.
Factual error: When Javert is singing "stars" he is walking a rooftop that appears to be another church across from Notre Dame. The church of Sainte Chapelle is in that direction, but looks nothing like what is depicted in the movie. Later when Javert has his solo on the bridge behind Notre Dame, the building he was standing on earlier should be visible from that angle, but was not included in the background.
Continuity mistake: Near the end of the "ABC cafe" number, the fellow who sings "they will come one and all" puts his hand on the arm of his comrade. When the camera goes to a wide shot a second later, he has put his hand down. (01:20:00)
Continuity mistake: The weather changes during the "Do You Hear the People Sing?" number, both of them. Wide shots show that it's bright and sunny but the close ups of Gavroche show that it's raining.
