A decent amount of talk has been dedicated to director Tom Hooper‘s decision to have the cast of Les Miserables sing live during takes instead of using the more traditional method of overdubbing. Rightfully so. Though it’s not the first movie to eschew dubbing, it’s the largest scale project to do so completely, and that creates a bit of danger in the form of raw voices. On the other hand, as cast members Hugh Jackman, Anne Hathaway, Amanda Seyfried, Russell Crowe, Samantha Barks and Eddie Redmayne explain, there’s a freedom that comes with it which allows for them to truly emote through their songs.

After a stunning teaser, this look into the method behind the madness proves once again that there’s a lot to hope for with this flick. It looks to be an epic given the proper epic treatment, and the on-set singing aspect, especially, gives it a fascinating edge that will most likely be something far beyond a simple gimmick. If nothing else, this featurette shows plainly the filmmakers’ investment in and dedication to the process.
