Roughly 100 films and documentaries will play at the 2015 Sundance Film Festival over the next 10 days. Why was the opening documentary chosen? Well, Sundance Festival Director John Cooper says he likes to choose a film that evokes emotion from the audience. Cooper tells TheStreet he chose Director Liz Garbus' 'What Happened, Miss Simone?' because it was 'both intense, and one that leaves the audience excited and engaged.' Separately, Cooper said he wants a film that has a broad reach, and this documentary certainly fits the bill. 'What Happened, Miss Simone?' was funded by Netflix and will be released on the video-streaming platform after the conclusion of the Festival. TheStreet's Leon Lazaroff reports from Park City, Utah.
