An actor or actress who continues to get A-list roles despite the fact that their films repeatedly bomb. To be a McConaughey, an actor or actress has their star-making role, followed by flop after flop to the point where audiences question why the performer continues to receive high-profile roles. Named after Matthew McConaughey, an actor dubbed as a rising star after his performance in Dazed and Confused, and continually called one despite the fact that every movie he has ever starred in (outside of romantic comedies) has flopped horribly.
Other examples of McConaugheys are Colin Farrell, Josh Hartnett, Orlando Bloom, and Halle Berry. The list of McConaugheys continually change and are always up for debate. Being a McConaughey is not permanent. The most famous example of an actor managing to reverse McConaughey status is Heath Ledger. Ledger was a McConaughey to the point of almost replacing McConaughey as the prime example until he starred in Brokeback Mountain.
