Matthew McConaughey keeps on shrinking.

On Friday Nov. 9, the "Magic Mike" actor, 42, turned up at Los Angeles International Airport to catch a flight to New Orleans -- looking completely transformed from his usual lean-but-muscular self.

Walking through airport security, McConaughey (sporting an 80-style mustache and shaggy hair) looked downright skeletal in a blue long-sleeved shirt tucked into baggy jeans.

The actor has shed his usually muscular body for a new film role in "The Dallas Buyer's Club," which tells the real-life story of Ron Woodruff, a drug addict in 1980s-era Texas who contracts HIV. Woodruff became one of the first AIDS activists and launched one of the first AIDS support groups.

In August, McConaughey told Us Weekly he was eating "small amounts" of high-protein, low-carb good to lose weight for the role. "I'll get down to the weight I need to get to," he said. "I'm on my way, and it's what I need to do for the job."

"I'm playing a guy who was sick and would have loved to have been healthier but wasn't," McConaughey explained. "For me, it's more of a mental thing than a physical thing."
