The Grapes of Wrath (2015)
If the reports of Spielberg wanting to produce a new version are borne out, it would actually be pretty interesting to see if they could do a new version and not PRECISELY duplicate ANY of the scenes of the 1940 classic.
They would have to figure out how to tell the story from completely new perspectives.
Of course many of the main plot details would remain but they would have to be framed very differently.
I would guess certain events only alluded to in the 1940 version (Tom's barroom fight which results in his manslaughter conviction, maybe Grandpa/Grandma's arriving with the first Joads in the 1880s, maybe Pa and Ma's visit to the World's Fair 35 years earlier) might be shown in flashback/non-linear storylines.
The first key choice of course would be director. From most reports Spielberg would not direct himself but concentrate on producer duties.
The Coen Bros?
