Simon Pegg is currently making the press rounds for his latest comedy thriller Kill Me Three Times, and he's been fairly open about the scripting process on Star Trek 3. The actor, who plays Scotty in the sci-fi franchise, took over as writer, working alongside Doug Jung to redraft a new version of the script once Roberto Orci was booted off the sequel. And it appears that Roberto Orci's screenplay was completely tossed aside to make way for the ideas had by incoming director Justin Lin. About this latest script, Simon Pegg tells Den of Geeks that it's a fresh take:

"It's completely new. I haven't read Bob (Orci)'s script and they didn't want us to. So we went back to the drawing board. We had creative meetings with Justin and there were things he wanted in there. I haven't written like this before. I've never been a custodian of something, it's usually mine what I'm writing. Whereas with this, you're given a bunch of stuff - 'Look we want this in it and this in it.' Or Justin will say - he's got an amazing visual mind, Justin. He's great at that kind of choreography. So he'll say, 'What if this happens?' So Doug and I go, 'Okay, right, let's try and get that into it.' So it's an interesting process."

Simon Pegg was approached to write the script by producers J.J. Abrams and Bryan Burk while they were all shooting Mission: Impossible Rogue Nation. Paramount apparently didn't like the direction Roberto Orci was taking the sequel, and he was removed as a director and replaced by Justin Lin. His script, which was written alongside newcomers J.D. Payne and Patrick McKay reportedly had the Enterprise, the Vulcans and a new alien race competing to get a time travel device. The Vulcans want to go back and stop the destruction of their planet, and the time travel storyline would have allowed Chris Pine and William Shatner to share the screen. While it sounded like William Shatner was ready to return, it is not known if that will still be the case. In an earlier interview Simon Pegg said that this new movie will retain the spirit of the original TV.
