“I went into one of the executive’s offices and I saw an ‘X3’ script, and I immediately knew it was a lot fatter,” Vaughn said. “I was like, ‘What the hell is this draft?’ He went, ‘Don’t worry about it,’ and I’m like, ‘No, no. I’m the director. I’m worrying about this draft.’ He wouldn’t tell me, so I grabbed it literally — it was like a crazy moment — opened the first page, and it said, ‘Africa. Storm. Kids dying of no water. She creates a thunderstorm and saves all these children.'”
Vaughn continued, “[I said] ‘What is this?’ [They said] ‘Oh, it’s Halle Berry’s script.’ I went, ‘OK, because she hasn’t signed up yet.’ ‘But this is what she wants it to be, and once she signs up, we’ll throw it in the bin.'”
Oh that’s very interesting. The script was actually written for it to be Kirk/Spock/McCoy rather than Kirk/Scotty/Chekov, but Nimoy and Kelley both said no because they were happy with where TUC left things for the TOS crew - which is why (for example) Chekov ends up running sickbay despite no evidence before of him having any medical training.
I’d never heard they had a version claiming Uhura would be there too.
