Remember when the ultimate guy's movie 300 gave the impression that Gerard Butler would be Hollywood's new macho-king? What the hell happened? Oh, right—he (and probably his agent, as well) shit the bed, curiously doing everything in his power to shun the dudes who saw 300 multiple times in theaters. For whatever reason, Butler thinks he's meant to be in romantic comedies, only he's not all that funny. He should've tried to become the next Mel Gibson; instead, he's turned into Matthew McConaughey's biggest threat.
