‘Les Miserables’ Trailer: Hear Anne Hathaway Sing! (VIDEO)

This December, Anne Hathaway, 29, will take on her biggest movie role to date in the adaptation of the hit Broadway musical Les Miserables, and Celebuzz has your first look at the official trailer!

Anne, who plays the ill-fated Fantine, is the main focus of the trailer, as she sings a stripped-down and heartbreaking version of the show’s classic number, ‘I Dreamed A Dream.’ Yes, we’re ready to cry, too!

What else do we see in the trailer?

Fans can also catch a glimpse of the film’s all-star cast, which includes, in no particular order: Hugh Jackman, as Jean Valjean; Amanda Seyfried, as Cosette; Russell Crowe, as Jarvet; and Eddie Redmayne, as Marius. Impressive, to say the least.

The film, which is already generating serious Oscar buzz, is director Tom Hooper’s follow-up to 2010’s The King’s Speech, which took home four Oscars in 2011, including Best Picture. Les Mis opens in theaters on Dec. 7, 2012.

The musical first hit Broadway in 1987, and went on to win a staggering eight Tony Awards, including Best Musical.

Like many of her castmembers, Anne — who chopped off her hair for the role — has sang time and time again, both in film and on the stage. For more on her epic voice, check out this clip from the Kennedy Center Honors, when Anne sang ‘She’s Me Pal’ for Meryl Streep. You can also watch a full version of ‘I Dreamed A Dream,’ as performed by one of the show’s original castmembers, Judy Kuhn, below.
