The worth of an Oscar

I just saw this article that discusses how an Oscar can impact the career of its winner. It evaluates what it might do for someone like Jamie Foxx compared to Hillary Swank, who took home Best Actor and Best Actress Academy Awards, respectively. Foxx's ability as an actor combined with his new Oscar will likely double his earning power, while Swank, who has taken home her second Oscar in five years, will probably have a tougher time defining herself beyond the tomboy roles she has often played. Also discussed are historical examples of how Oscars affected the earning power of people such as John Wayne and Gene Hackman.
