We hope you're planning on bringing your tissues to this one -- we've got the official trailer for 'A Late Quartet,' a moving musical drama starring Philip Seymour Hoffman, Catherine Keener, and Christopher Walken.

'A Late Quartet' premiers tonight at the Toronto International Film Festival before it hits theaters here on November 2. The film stars Christopher Walken as a famous cellist and member of a world-renowned string quartet who receives a devastating diagnosis from his doctor. Upon discovering what that is, he moves to have the first concert of his quartet's season be his last -- and it also happens to be the group's 25th anniversary. The upsetting news throws the group into a spin, with hidden egos emerging, competition stirring, and the love between Philip Seymour Hoffman and Catherine Keener's characters put to the ultimate test.

The film was inspired by Beethoven's Opus 131 String Quartet in C-sharp minor, and Christopher Walken provides a rather informative voiceover, explaining the seven movements and how they connect, how they are played without pause or intermission, and the way each part is inextricably linked -- it's heavy-handed metaphorical stuff, but the trailer coupled with the compelling music from the opus is admittedly beautiful stuff. And with a cast like that? Consider us intrigued.
