The 16th Full Frame Documentary Film Festival begins Thursday at various locations in downtown Durham and runs through April 7. For the first time, Full Frame is a qualifying event for the Academy Awards for best documentary short and the Producers Guild of America Awards, which means that along with meeting other criteria, films can be considered for those awards by being shown at Full Frame, without the usual theatrical run. This year, the festival, part of Duke University’s Center for Documentary Studies, has as its theme “Stories About Stories.” Filmmaker Amir Bar-Lev has chosen nine films, including two of his own, to explore the place where truth and perspective meet. Fifty-one features and shorts, selected from 1,200 submissions, will be screened as part of Full Frame’s “New Docs” program, making them eligible for the Audience Award and other juried prizes. Winners will be announced April 7.
