DuVernay, the filmmaker of "Selma" and the Netflix documentary "13th", said that the power of movies is the ability to "speak to each other through cinema".
In the festival's Un Certain Regard section is "Rifiki", a lesbian romance from Kenya that has already been banned at home. The film, 20 years in the making, stars Adam Driver as a man warped into the fantasy world of medieval Spain.
