Directors Valerie Faris and Jonathan Dayton don’t work very often, but when they do decide to make a movie, it’s always been something worth paying attention to. The “Little Miss Sunshine” and “Ruby Sparks” helmers return with “Battle of the Sexes,” which dramatizes the famous 1973 tennis match between 29-year-old Billie Jean King and 55-year-old Bobby Riggs, with both sides playing for the glory and dignity of their gender on national television. It was a publicity circus meant to playfully poke at period resentments during the era of the Women’s Liberation Movement, but Dayton and Faris aren’t interested in manufacturing a straight recreation of the match. They, along with screenwriter Simon Beaufoy, cut deeper, studying the tentative lives of the players as they struggle with domestic issues and, for King, burgeoning sexuality during a rocket ride to nationwide fame. True to form, the pair treat the subject with care, and make a stirring, colorful, and amusing effort, finding different ways to approach an oft-told tale.   Read the rest at Blu-ray.com
