O Brother, Where Art Thou? (2000)

Continuity mistake: When they first meet George Nelson, the left back seat window is half way open. A few seconds after they get into his car, Delmar gives the machine gun to Nelson through the left back seat's completely open window (the camera shows the guys all the time so we can see that Delmar didn't lower the window when he got in the car). (00:32:25 - 00:33:40)

Washington Hogwallop: Mrs. Hogwallop up and R-U-N-N-O-F-T.

Trivia: George Clooney (Everett) was going to sing "Man of Constant Sorrow" for the film but his singing voice was very poor so he ended up lip-synching the songs instead. He said "I'm not my aunt [referring to the late singer/actress Rosemary Clooney, best known for her role in "A White Christmas" (1954)]. I decided it would be easier to just do a passionate lip-sync." He was so nervous that the tapes of his singing would get out that he returned to the studio to ensure all the evidence had been erased. The musical director of the film confirmed this but said "George is a very good singer but that style of music is very difficult and one almost has to grow up singing it in order to sing it convincingly. George did a really good version of the tune but it wasn't as good as he wanted."

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?
