Dyeing for Your Art: For the film Anne Hathaway had her hair cut short on camera and lost 25 pounds to make it look like she was dying. Hugh Jackman lost 30 pounds, shaved his head, and grew a scraggly beard for the scenes where Valjean was a convict, even going 36 hours without water. Talk about this to the extreme.
Enforced Method Acting: According to the DVD commentary, the entire barricade building sequence was done by the actors themselves in real time, which was around 15 minutes, and the director's only instructions were four words: "Build a barricade. Action!"
Fake Nationality: The French characters are played by Australian, American and British actors.
Real-Life Relative: Russell Crowe's son, Tennyson, appeared in "Do You Hear The People Sing?" as one of the street urchins, waving the red flag, with Gavroche.
Saved from Development Hell: A film adaptation of the musical was discussed for many years; the 1991 souvenir program for the stage show claimed it was coming out in 1993 via TriStar Pictures. Universal Pictures was the studio that finally brought the movie to the light of day in December 2012.
The original cut is 4 hours with a 15-minute long battle sequence. But Hooper trimmed it down to 2 hours and 37 minutes which results to some songs cut with some scenes from the trailers not appearing in the final version of the movie, such as the last part of "The Confrontation" where Valjean and Javert continues singing the last stanza of the song in a form of a Distant Duet.
