Matthew Marc Cushman, generally credited as “Marc Cushman”, is a writer who wrote together with Jake Jacobs the original story for the Star Trek: The Next Generation third season episode “Sarek”. Cushman’s and Jacobs’ unpublished story was later rewritten by Peter S. Beagle who also wrote the teleplay.

Cushman is also the primary co-author of the unauthorized reference book These Are the Voyages: TOS Season One, which was released in August 2013. The follow-ups of the book, dealing with the second and third seasons of Star Trek: The Original Series respectively, were released in 2014 and 2015 respectively. Cushman embarked on the project in 1982 when he, “(…) was happily assigned the job of meeting with Gene Roddenberry and interviewing him for a television special I was hired to write on the Star Trek phenomenon. This was in 1982 for a Los Angeles-based company that made programs of that type for local TV. Gene was wonderfully gracious and giving, with both his time and materials — he provided me with all the scripts from TOS, along with numerous other documents.” Amazed at the sheer amount of documents Roddenberry still had in his possession, the idea germinated, spurred on by Roddenberry by giving Cushman a letter of endorsement, to have all these incorporated into a book about the production of The Original Series. Ultimately, the project would become three decades in the making, with frequent meetings with Roddenberry and other Original Series production staffers, like Robert Justman and D.C. Fontana. It was during one of his many meetings with Roddenberry that Cushman pitched his story for “Sarek”.

On “Sarek”, Cushman was interviewed in a special feature on the 2013 feature-length Unification Blu-ray disc release.
