One of the best films I saw at Sundance this past January was director Craig Johnson’s dark comedy The Skeleton Twins.  The film stars Bill Hader and Kristen Wiig as estranged twin siblings who are drawn back together after Hader’s character tries to commit suicide.  It’s at once sweet, funny, and sad, and Hader turns in a genuinely terrific dramatic performance.  Despite the serious subject matter, the picture has well-placed moments of humor, and in anticipation of the film’s release on home video, we here at Collider have been provided with an exclusive clip from one of the featurettes.  This behind-the-scenes clip focuses on the improvisation in the picture, with candid (and very funny) footage of Hader and Wiig trying to keep it together on set.

Watch the Skeleton Twins featurette after the jump.  The film will be released on Digital HD on December 2nd and on Blu-ray/DVD on December 16th.  I highly recommend checking it out.
