Meyer is one of the biggest names in Star Trek production history, having essentially relaunched the series, along with writer/producer Harve Bennett, when he directed The Wrath of Khan (which uncredited he largely rewrote too). He later wrote both The Voyage Home and The Undiscovered Country, the latter he directed too. So basically he made all the good TOS movies!
Bryan Fuller had this to say in a statement posted by StarTrek.com:
Nicholas Meyer chased Kirk and Khan 'round the Mutara Nebula and 'round Genesis' flames, he saved the whales with the Enterprise and its crew, and waged war and peace between Klingons and the Federation. We are thrilled to announce that one of Star Trek's greatest storytellers will be boldly returning as Nicholas Meyer beams aboard the new Trek writing staff.Together with Fuller, and nuTrek writer Alex Kurtzman, the series now has three generations of
Trek creators as producers, as well as newbie Heather Kadin. Hopefully they can bring the best of all generations to make something really amazing!
The new, as yet untitled Star Trek series, of as yet unknown setting, is due to start early next year. The first episode will air in the US on the CBS Television Network, but subsequent episodes will be available exclusively on the the CBS All Access on demand streaming service. International distribution has yet to be detailed.
