Now, according to Deadline, Orci isn’t anymore.
Whether he was fired or quit the project is unknown, as very few details beyond “he’s out” seem to be around. Orci is still “Producing,” but it’s unclear whether or not he’s actually acting as a real producer or “Producing” the way Tim Burton was a producer on Batman Forever. Deadline says Edgar Wright is on the short list to replace Orci, but that seems weird and unlikely. Wright is a great director, but how well his style would mesh with the Star Trek franchise is questionable.
Although it’s true “Edgar Wright’s Star Trek” would probably be entertaining.
