The American Film Institute/Discovery Channel presents the Silver Docs Film Festival, now in its ninth year. The event closes this Sunday, June 26, but not before some films of particular interest to the LGBT community, including Jerry Rothwell's Donor Unknown, about a woman raised by lesbians who seeks out her birth-father; Eric Drath's Renee, about pioneering transgender tennis player Renee Richards; Lee Hirsch's The Bully Project, which examines the "urgent crisis in American society" of bullying; and Bob Hercules and Gordon Quinn's A Good Man, which looks at celebrated gay choreographer Bill T. Jones as he works on a piece honoring Abraham Lincoln. All films screen at AFI's Silver Theatre and at the Discovery HD Theater at Discovery Communications World Headquarters, in downtown Silver Spring. Tickets are $11 per screening.
