Sources close to the production tell TMZ, the filmmakers originally offered the role to Von A-Hole himself -- but he honorably declined ... in favor of letting Mr. Pitt take the reigns.
As for who will play Zsa Zsa -- we're told producers want a "gold-digger type" ... and so far, the front-runners are Nicole Kidman and Drew Barrymore.
No word on whether Brad Pitt will actually take the part -- but based on the uncanny resemblance (*cough cough) we can't see why on Earth he wouldn't ... that is, if the movie ever gets made.
