Abrams’ “Star Trek XI” at Paramount.He says “The head of production at Paramount called my agency to tell them about this project and they are aware of Bill’s and my contribution to the franchise, and they’d like us to know they might want some involvement. It was all very, very general. They might possibly want Bill and I to set up the story as a flashback. But that’s just conjecture on my part”.
