The movies most commonly associated with the Sundance Film Festival are indie darlings -- daring dramas like "Sex, Lies and Videotape," moody meditations like "Garden State" and surprising comedy gems like "Little Miss Sunshine." But Sundance is always a hub for the year's hottest documentaries. "Hoop Dreams," "Super Size Me" and "Man on Wire" all premiered there, after all. In fact, two of 2016's Oscar-nominated documentaries -- "Cartel Land" and "What Happened, Miss Simone?" -- were highlights at last year's festival, while "Going Clear," "Kurt Cobain: Montage of Heck," "Best of Enemies" and "The Hunting Ground" also bowed this time last January.
