Matthew McConaughey's transformation from 'Magic Mike' stud to the frail character in 'The Dallas Buyers Club' is the most astounding one from recent memory. In the true-to-life film, he plays Ron Woodroof, a Texan straight man diagnosed with AIDS and who, in response to the failing effects of the only AIDS medication available at the time, started an underground non-toxic drug ring.

Back in July of 2012, McConaughey sat down with Larry King to discuss the role, at which time he revealed he essentially starved himself, forcing his body to feed off itself. "I’ve lost about 15 pounds, I’ve gotta lose about 15 more," he said. "I should not look healthy by the time I’m done doing this."
