Movie enthusiasts and cheap dates unite! Peachtree TV's SCREEN ON THE GREEN is back in Piedmont Park for another summer of movies and mayhem, starting with National Treasure. Though this year's lineup doesn't glitter as much as years past – Transformers: Revenge of the Fallen, slated for June 3, is an especially repulsive selection – the annual film fest still offers music by DJ Cowboy, a scavenger hunt, a trivia contest and X-marks-the-spot bingo. Or skip the child's play and show up at dusk to watch the flick on a ginormous screen under the stars. Through June 24. Free. Thurs., 6 p.m. 400 Park Drive. www.peachtreetv.com/screenonthegreen.
