Shot in a “Blair With Project” vérité style, “Trollhunter,” which gained attention in the Midnight section at Sundance 2011, is the story of a group of Norwegian film students that set out to capture real-life trolls on camera after learning their existence has been covered up for years by a government conspiracy. A thrilling and wildly entertaining film, it mixes impressive visual effects with Norwegian folklore. (Dir. André Øvredal)
