Actor and 30 Seconds to Mars frontman Jared Leto is stepping before the cameras for the first time in three years for The Dallas Buyer’s Club , joining Matthew McConaughey and Jennifer Garner in the long-in-the-works AIDS drama. Canadian director Jean-Marc Vallee (The Young Victoria) is helming the project, which will begin shooting next week in New Orleans. Inspired by real events, the story centers on Ron Woodroof ( McConaughey ), a Texas electrician diagnosed with AIDS and given six months to live, who began smuggling alternative drugs into the U.S. to help himself and other AIDS patients. He added years to his life but rushed headfirst into a collision course with the U.S. Food and Drug Administration, which was bent on keeping the drugs out of the country. In a potentially standout role, Leto would play a flamboyant cross-dresser with HIV who helps Woodroof. At one point, Gael Garcia Bernal circled the role but never reached the dealmaking stage.
