Casting for a remake?
Betty -- Ellen Page
Bob -- Topher Grace
Ma Kettle -- Meryl Streep
Pa Kettle -- Billy Bob Thornton
Crowbar -- Wes Studi (a more dignified interpretation than we're used to)
A new version would have to stick closer to the original book -- hint at a little grim desperation under the humor. Except the portrayal of Native Americans would have to be a bit more thoughtful, and MAYBE a happy ending for these two kids might be procured.
