Sharon Leal, most widely known for her thankless role as the replacement for Jennifer Hudson’s Effie in the film version of “Dreamgirls,” gets her chance to be the headliner in the steamy “Addicted,” opening Friday. Based on a novel of the same name by erotic pop-fiction author Zane, the movie wasn’t available for advance screening but is generating buzz among its primary target audience, women of color. Leal plays Zoe Reynard, a successful art gallery owner with a doting husband and kids whose world is rocked by an out-of-control affair with smoldering painter Quinton Canosa (Cuban telenovela star William Levy). Is it the black “50 Shades of Grey”? Maybe not, but it sounds pretty darn close.
