5. John Goodman - O Brother Where Art Thou?
John Goodman is well credited for his Coen brothers cameos, with only previous entry Steve Buscemi appearing more times in their movies than him. The film is set in the 1930s Deep South, and follows George Clooneys trio of escaped convicts. Goodman plays Big Dan Teague, a well spoken, well fed, eye patched Bible salesman. His lunacy isnt apparent on first meet, but it isnt long before he reveals some haywire tendencies. After having a picnic lunch with Clooney and Tim Blake Nelson, Teague thanks the pair for the lunchtime conversational hiatus, explaining how he prefers to refrain from speech during gustation. Normal enough so far (kind of). Then, after launching into some bible selling spiel, he decides to beat Nelson and Clooney across the heads with a thick tree branch, before stealing their money. The other scene he appears in reconfirms the characters innate insanity, cropping up as a leader of the Ku Klux Klan and performing a sacrificial ritual, eventually foiled by Clooney and co.
