The movie I'd love to reimagine and restoryboard is Gone with the Wind. That final scene on the stairs when Rhett walks out and leaves Scarlett weeping on the stairs? I mean, she's a pretty terrible character the whole way through and kind of deserves it, but still! What an ending!
I can imagine a ton of pan shots around the house, too, to show off how the environment has changed after the war, their time together. . . that's such a huge indication of everything that's happened.
