Matthew McConaughey isn't the only "Dallas Buyer's Club" star to shed an alarming amount of weight for the upcoming drama, which premiered Wednesday at the Toronto International Film Festival.
Jared Leto, part-time 30 Seconds to Mars frontman and part-time actor, got his weight down to a startling 114 pounds to play an AIDS-stricken transexual woman named Rayon, who conspires with McConaughey's character to traffic medications from around the world.
