MATTHEW MCCONAUGHEY's frightening weight loss!

Matthew McConaughey has had many different looks in the movies but this one is EXTREME!! This is serious dedication to the job!

He lost about 30 lbs. to play a real-life HIV-positive AIDS activist named Ron Woodruff for a movie called "The Dallas Buyer's Club". He was photographed at the LA airport on Friday (below). It is certainly a different look than his last movie "Magic Mike" (picture to the left) where he played a male exotic dancer. No word yet on when this new movie will be released...or when Matthew will be back to his old fit self for all the women to enjoy!
