The Free Associates' new fully improvised one-act, which pokes fun at Anne Rice novels, follows the company's usual formula for parody. As in shows like Cast on a Hot Tin Roof and BS, the cast steep themselves so thoroughly in the material that parts of the show could pass for a stage adaptation, though a somewhat twisted one. This technique yields some interesting and entertaining insights into Rice's fiction, most notably her tales' hothouse homoeroticism. But for all the care these improvisers lavish on looking and acting like foppish, self-centered vampires, the performances lack the crazy, playful, innocently campy energy of the work the Free Associates created under their erstwhile founder, Mark Gagne. Through 11/12: Fri 8 PM, Sat 8 and 10 PM. Hull House Center for Arts and Culture, 1136 W. Wilson, 312-458-9083. $15.
