“Battle of the Sexes” (Fox Searchlight), about the famed 1973 tennis match between Billie Jean King and Bobby Riggs, is that rare movie that successfully combines biography, sports and queer subject matter for a thoroughly entertaining and educating experience. First and foremost, credit goes to co-directors Jonathan Dayton and Valerie Faris (Oscar-winner Little Miss Sunshine). Even though we know the outcome (King walloped unrepentant male chauvinist pig Riggs), they managed to make it feel fresh and exhilarating.
