While we're on the subject—and since this is, after all, the Shakespeare and Film Microblog—there was a moderately-successful film version of A Thousand Acres as well.
I'd like to touch on two scenes. First, the "division of the kingdom" scene is as understated in the film as it is in the novel. From this small moment springs much of the rest of the tragedy:
Here's the equivalent of the end of Act II of Shakespeare's King Lear. The Iowa storm captures the fierceness of the elements—and Larry's (i.e., Lear's) anger and madness in venturing out in it.
