Elvis Costello isn't happy with filmmaker Jared Hess, who, Costello says, refused to credit him for the name to his smash 2004 film, 'Napoleon Dynamite.' Costello fans have long recognized the moniker as Costello's mid-'80s alter-ego.

Hess maintains that the name of his outcast movie character was something he dreamed up, but Costello firmly disputes that notion. "The guy just denies completely that I made the name up," Costello tells Spin in its December issue. "But I invented it."

"Maybe somebody told him the name and he truly feels that he came about it by chance," Costello continues. "But it's two words that you're never going to hear together."

Kind of like Costello and modest.
