CBS Films is pulling out the big guns ahead of Inside Llewyn Davis’s December 20 release date. And by big guns, we mean a bearded Justin Timberlake starring intently at Oscar Isaac. Oh, and singing. Plus, Adam Driver wearing a black cowboy hat and yelping absurdities. The trio is extremely charming, which you probably already guessed from any of the film’s trailers. It’s a smart move releasing a full JT scene. Few things reel in an audience like Timberlake operating at peak earnestness.
