ETA-- It reminds me of Matthew Vaughn's story about the "Hallie Bailey script" for X-Men 3 that was created just to get her to sign on to the movie.

“One of the main reasons I quit X-Men 3, and this is a true story. Hollywood is really political and odd,” Vaughn said during NYCC (via ScreenRant). “I went to an executive’s office and I saw an X3 script. It was a lot fatter. I asked, ‘What is this draft?’ They were like, ‘Don’t worry about it.'”
He continued, “So I grabbed it, and opened the first page, and it said, ‘Africa. Kids dying from no water, and Storm creates a thunderstorm to save all these children.’ I thought it was a pretty cool idea. I said, ‘What is this?’ They said, ‘This is the Halle Berry script because she hasn’t signed on yet. This is what she wants it to be. And once she signs on, we’ll throw it in the bin.’ I thought, if you’re going to do that to an Oscar-winning actress who plays Storm, I quit. I thought I’m mincemeat.”

That is seriously effed up... and an excellent example of why stars who have the clout might want to consider contractually locking in certain scenes/script versions, etc.
