A 42-minute making-of documentary, "Inside 'Inside Llewyn Davis,'" produced and directed by David Prior. A number of cast and key crew people are interviewed, but, not surprisingly, the Coens, music supervisor T-Bone Burnett, and lead Oscar Isaac dominate the proceedings.

A seasoned sheriff investigates a dead body in the woods and calls on an old pal, a medical examiner, to help piece together a series of chilling events.
