This year’s slate also includes three films that are on the short list for Oscar nominations for Best Documentary. Those include Josh Fox’s Gasland, which questions the safety of Halliburton’s natural gas drilling technology, known as “fracking” or hydraulic fracturing. That film will be screened Jan. 22, 7 p.m., and will feature an appearance from Mr. Fox. (NOTE: Gasland was originally scheduled to be shown Jan. 23. Waste Land, which was scheduled for Jan. 22 has been moved to Jan. 23 at 1:30 p.m. That screening will feature a talk by TerraCycle CEO Tom Szaky.)
