The Plaza Theatre presents THE WIZARD OF OZ with more tricks up its sleeves than the colorful characters of the classic film. Karl Slover, who played several of the Munchkin roles in the film, will be on hand to sign autographs and pose for pictures prior to the screening and will also give a brief introduction, speaking about his time in the magical land of Oz. Costumed characters will mill around while singers and dancers celebrate the film's score, all in conjunction with the Plaza's Film Festival celebrating the historic theater's 70th anniversary. $6.50-$10. Sat.-Sun., 2:30 and 9 p.m. 1049 Ponce de Leon Ave. 404-873-1939. www.plazaatlanta.com.
