• 2016 Screen Actors Guild Awards: 'Welcome to diverse TV'

The historical slave rebellion drama had already broken the acquisition record when Fox Searchlight scooped it up for a cool $17.5 million, and quickly became the must-see of the festival, commanding reported $100 offers for tickets.

"I've poured everything that I am into making it," Parker said following the film's premiere on Monday. "I made this film for one reason, with hope of creating change agents, that people could watch this film and be affected."

Diversity concerns

This win for a movie with a black director and a largely black cast is significantin the midst of an award-show season that's been mired in controversy about diversity.

Prominent black people in the entertainment industry, including director Spike Lee and actress Jada PinkettSmith, have vowed to boycott the Academy Awards, after the academy announced an all-white list of acting nominees for the second year in a row. The hashtag#OscarsSoWhite made a resurgence on Twitter.

The recent Screen Actors Guild Awards stood in contrast with a comparatively diverse group of winners, including Queen Latifah,Uzo Aduba, Viola Davis and Idris Elba.

Other big winners at Sundance included the Anthony Weiner documentary Weiner,which took home the U.S. documentary grand jury prize, and Jim: The James Foley Story,which won the U.S. documentary audience award.

Daniel Scheinert and Daniel Kwan also won the U.S. dramatic directing award for their wildly divisive film Swiss Army Manabout a man stranded on an island (Paul Dano) who discovers a flatulent corpse (Daniel Radcliffe).

The 32nd Sundance Film Festival wraps on Sunday.
