O Brother, Where Art Thou? (2000)

Question: The only way that the valley could be flooded by rampaging water is that a dam was broken up river. Otherwise the water rises very slowly. Does the movie explain this? If so I missed it. In which way was that river flooded?

Question: In the KKK scene, Homer Stokes says "The color guard is colored." Did he mean this literally, like Everett was a black man, or did he mean that he was white (unlikely because John Goodman is white and so is he), or is he mistaking Everett for a black man because of his dirty face?

Question: Is there a scene in the movie where we see Everett find the gold watch in the drawer while he is looking for a hairnet? It's not on the dvd and I am sure I have seen it. My family says they have never seen it so it's driving me crazy.

Question: The scene when the Ku Klux Klan are assembling is very similar to the scene in "The Wizard of Oz", when the scarecrow, the tin man and the cowardly lion sneak into the witch's castle. The marching music, the disguises and the way they enter the procession are almost identical. Was this intentional?
