We saw that Jared Leto lost a lot of weight to play a flamboyant cross-dresser with HIV in The Dallas Buyers Club in these set photos. But there he was covered by a bulky fur coat. To show off his dramatic transformation, Leto recruited photographer Terry Richardson for a shirtless shoot, and oh my goodness! Leto has become the kind of skinny that is hard to look at. I admire his commitment to the role, but I can’t imagine a scenario in which the verisimilitude is worth the health issues.Matthew McConaughey has also drawn attention for his weight loss to play the lead role in Dallas Buyers Club, based on the true story of Ron Woodroof (Matthew McConaughey). Woodroof was given six months to live after a 1986 AIDS diagnosis, but instead survived six years on the medication he smuggled into the U.S. that he shared with other patients. Jennifer Garner co-stars in the Jean-Marc Vallée-directed drama. Check out the Leto photos after the jump.See more at Richardson’s Tumblr [via Just Jared]:For comparison, here's what Christian Bale wasted away to for his role in The Machinist:christian bale the machinistThey all crazy.
