Doug Jones (Pan’s Labyrinth) plays Lt. Saru, a science officer. Saru is a new species of alien.

Speaking to EW about his character, Jones teased: 

[Producers] said Saru is the Spock of the series, he’s the Data of the series — and those are beloved characters that I always connect with whenever I would watch the past incarnations of Star Trek.

On Falling Skies, I played an alien species who came to Earth to help the humans fight back the bad aliens who’d taken over, and I was intelligent, well-spoken, had a lot of answers and science-y smart. Saru is all of those things and then some.

Star Trek: Discovery Production

Gretchen Berg and Aaron Harberts assumed the role of showrunners after Bryan Fuller stepped away from the show, with Akiva Goldsman getting a “top creative role.”

Alex Kurtzman also executive produces the new show, and had this to say about the process:

Bringing Star Trek back to television means returning it to its roots, and for years those roots flourished under Bryan’s devoted care. His encyclopedic knowledge of Trek canon is surpassed only by his love for Gene Roddenberry’s optimistic future, a vision that continues to guide us as we explore strange new worlds.

Kurtzman was previously one of the masterminds of the recent Star Trek films that were directed by J.J. Abrams. He co-wrote Star Trek (2009) with Roberto Orci, and he also co-wrote Star Trek into Darkness (2013) with Orci and Damon Lindelof. 

Star Trek: Discovery — What Led to Bryan Fuller’s Exit

Nicholas Meyer, the director and uncredited co-screenwriter of The Wrath of Khan, will serve as a consulting producer on Star Trek: Discovery

Other writers include: Ted Sullivan, Erika Lippoldt, Bo Yeon Kim, Craig Sweeney, Sean Cochran, and Tyler Dinucci.
