Famous Oscar Feuds

With Billy Crystal at the helm, feel-good "The Artist" poised to sweep, and even the best-actor competitive pool filled with brotherly love (and sexiest men), the 84th round of the Academy Awards promises nothing but what the Oscars are meant to be: a feel-good if not familial, star-studded reunion with swanky outfits. No cage fighting. No backstabbing. Heck, even the Muppets are presenting. You call this entertainment? Think of this Sunday as a breather, an escapist episode in an escapist industry. But if all this goodwill makes you spoiling for a good feud, you don't have to look back far for some awkwardly memorable moments of insults gone awry, ruffled sensitivities, and even sibling rivalries that span decades. Take a spectator seat -- and a safe distance -- at five Oscar feuds for the ages. -- By Vera H.C. Chan
