The Coen Brothers' Inside Llewyn Davis is terrific, and it's also probably the duo's saddest movie.  However, it also has some hilarious moments, and its funniest scene by far is when struggling folk singer Llewyn Davis (Oscar Isaac) reluctantly plays "Please Mr. Kennedy" with his friend (Justin Timblerlake) and another musician (Adam Driver) who has a unique approach to the song.  I've recommended holding off on listening to the song until you see the movie, but that's because I wanted you to see Driver performing it.  Now you can, and you absolutely should.  There's also a new featurette, which does a good job explaining the music's role in the production and in the story.

Hit the jump to check out the clip and featurette.  The film also stars Carey Mulligan, Stark Sands, Garrett Hedlund, and John Goodman.  Inside Llewyn Davis opens December 6th.

Here’s the official synopsis for Inside Llewyn Davis:

INSIDE LLEWYN DAVIS follows a week in the life of a young folk singer as he navigates the Greenwich Village folk scene of 1961. Guitar in tow, huddled against the unforgiving New York winter, he is struggling to make it as a musician against seemingly insurmountable obstacles—some of them of his own making.
