Matthew Mcconaughey is set to stun his legions of admirers by packing on the weight to play an over-the-hill bar brawler in new movie THE GRACKLE. The movie hunk, who is famous for his toned stomach, will let his fitness regime slide a little when he plays his upcoming role - and he fears some fans will think he's slacking for real. He says, "My character... needs to be bull strong but meaty. Watching it happen will be fun. "There should be some funny stories in the tabloids because I'll still have to go out and get my belly tan."
