O Brother Where Art Thou. Location finding

I've chosen to base my project on O Brother Where Art Thou. I like the style of the film with the sepia toning and there is a large variety of settings to play with.

Possible locations for different scenes.

• Opening scene: Running away through cornfeields.

• Running down the road shackled together carrying a live chicken

• Running away from burning barn through farm yard.

• Campfire in the forest

I am also interested in doing an underwater shoot for the scene where the damn gets exploded and washes them away.
