"Gone With the Wind" author Margaret Mitchell's first choice to play Rhett Butler was Groucho Marx! And we wonder why writers don't get no respect in Hollywood!

180 degree about face: how about miscasting that worked out fine? I'm thinking of the "voice-acting" job that Eddy Murphy did in "Schrek". Whoever would have expected that he could portray a talkng jackass so well?

(Truth is: I loved it, but that line was too much to resist.)
