Jared Leto, who signed on to the flick just a few weeks ago, has already undergone a dramatic transformation for his part in the drama -- debuting a newly scary-skinny bod, and shaving off his eyebrows -- in order to play a transsexual woman with AIDS in 1980s Texas.
Despite his intense weight-loss process -- Leto told Vulture at the IFP Gotham Awards in New York on Tuesday that he's been fasting for the last month or so -- the actor says he's more concerned with mastering his character's grooming techniques, like waxing his body (and facial) hair.
"Your body goes through weird stages [when fasting]," he shared. "Sometimes it's hard to hold on to water. But for me, it's not about the most weight I can lose, it's more to represent the character. I'm focused on what it means to be a transsexual woman."
As hungry as he might be (he admitted to feeling lightheaded), Leto, 40, is also doing his best to look on the bright side.
