Filmmaker David Roach started the Oakland International Film Festival back in 2002 with the goal of supporting Oakland’s burgeoning independent filmmaking community. Twelve years later, the festival includes 42 local and international films, and spans four days and three cities, with screenings at The Grand Lake Theater (3200 Grand Ave., Oakland), Geoffrey’s Inner Circle (410 14th St., Oakland), the Black Repertory Group Theater (3201 Adeline St., Berkeley), and the Historic BAL Theatre (14808 E. 14th St., San Leandro). The festival kicks off on Thursday with Toussaint L’Ouverture, a film about the leader of the Haitian Revolution. Local films focus on both current and historical topics: A Confused War documents Richmond’s efforts to reduce violence and Thrown for a Loss: The Story of the 1963 Pittsburg Mallards tells the story of a youth football team that was on its way to meet President John F. Kennedy when he was assassinated. Emphasizing community development, the festival will also hold a film “market” on Saturday, during which local filmmakers will showcase ten-minute clips of their work to potential funders.
