Watch: Samantha Barks Sings "On My Own" In Latest 'Les Miserables' Trailer Plus New Featurette

nullYou want to know how popular "Les Miserables" is? Not only is it the biggest advance ticket seller this Christmas, it has broken the previous record held by "Sherlock Holmes." So yes, a lot of people will be going to see the epic musical next week, but in case you need an extra nudge to get off the couch and go, another trailer has arrived.

This latest spot shines the light on newcomer Samantha Barks, who reprises her role of Eponine which she played to acclaim on stages in the U.K. Here, we get to listen to her sing "On My Own," as an array of new and old footage show off the size and scope of the film, which is certainly among one of the biggest productions hitting screens this holiday. And to get an impression of just how much work went into the movie, a new featurette has arrived about the construction of the sets, which again, are massive.

"Les Miserables" waves the flag on December 25th.
