The Hollywood Reporter is claiming that two new writers will be working with Roberto Orci on Star Trek 3.
For the last two Trek movies, Orci wrote the script along with Alex Kurtzman and Damon Lindelof.
The two new writers are J.D. Payne, and Patrick McKay.
Both writers have worked with J.J. Abrams before, on Boilerplate, which was produced by Abrams.
