A quick note for film aficionados: The 2011 edition of the Sundance Film Festival is now underway. And over the next two weeks, The YouTube Screening Room will bring you short films from festivals past and present. Right now, you can watch four new films by up-and-coming directors – 8 Bits, Andy and Zach, The High Level Bridge, and Skateistan: To Live and Skate in Kabul (above). More new films will be added on January 27th and February 3rd. In the meantime, you can catch several other short films that originally played at Sundance, or were made by Sundance Institute alumni.
