The Hudsucker Proxy

When Waring Hudsucker, head of hugely successful Hudsucker Industries, commits suicide, his board of directors, led by Sidney Mussberger, comes up with a brilliant plan to make a lot of money: appoint a moron to run the company. When the stock falls low enough, Sidney and friends can buy it up for pennies on the dollar, take over the company, and restore its fortunes. They choose idealistic Norville Barnes, who just started in the mail room. Norville is whacky enough to drive any company to ruin, but soon, tough reporter Amy Archer smells a rat and begins an undercover investigation of Hudsucker Industries.

The Hudsucker Proxy is a 1994 screwball comedy fantasy film written, produced and directed by Joel and Ethan Coen. The script was co-written by Sam Raimi, who also served as the second unit director. The Hudsucker Proxy stars Tim Robbins, Jennifer Jason Leigh, Paul Newman and Jim True-Frost, and depicts the story of Norville Barnes, a naive business graduate who is installed as president of a manufacturing company as part of a stock scam.
