Sundance Film Festival hit “Trouble The Water” is among the films being funded with the next round of support from the non-profit group. Sundance Institute will back the doc with an audience engagement grant in the wake of its recently announced distribution deal with Zeitgeist Films. Eighteen other documentary film projects have also been selected for support from the Sundance Documentary Fund. The organization will provide more than $500,000 in funding for both emerging and established filmmakers, backing production and outreach efforts. Some 325 applications were received from more than 52 countries for this round of funding.
