OK, so let me get this straight. The treatment Bradbury handed in was intentionally crap, based on what he thought the producer wanted-- and that's THE ATOMIC MONSTER/GROUND ZERO. Right?

Then he gets notes, and does a polish of that. Yes?

(Is it essentially the same story? Is it what Alland describes, above?)

And then he hands in IT CAME FROM OUTER SPACE and that's the usual poetic Bradbury stuff. And everybody loves it, adopts it as their own, etc., etc. And they hire Harry Essex to trim it down and put it into a workable shooting script format.

I really refuse to shell out a hundred bucks for that published collection of this stuff, but it'd be interesting to know.
