With DARK PLAY OR STORIES FOR BOYS, Actor's Express continues Tues., SEPT. 11, with a work that promises to offer the theater's characteristic blend of edginess and eroticism. A hit of the 2007 Humana Festival of New American Plays, Carlos Murillo's script depicts a teenage boy who creates a fictional online identity and sets off a chain reaction of obsession, deception and danger. Freddie Ashley, new artistic director of Actor's Express, directs John Benzinger, Stephanie Bruno, Jimi Kocina, Stacy Melich and Brent Rose. Through Oct. 6. $21.50-$27. Wed.-Sat., 8 p.m.; Sun., 5 p.m. 887 W. Marietta St. 404-607-7469. www.actors-express.com.
