The Walking Dead star Sonequa Martin-Green is boldly going to CBS All Access.

The actress, currently a series regular on the AMC zombie drama, has booked the starring role on Star Trek: Discovery, The Hollywood Reporter has confirmed. CBS All Access and producers CBS Television Studios declined comment.

Martin-Green — who will continue to portray fierce survivor Sasha on Walking Dead as a series regular — will play a lieutenant commander on Discovery. It's also worth noting that Walking Dead has already wrapped production on its current seventh season and, should Martin-Green's Sasha survive, wouldn't return to production until summer 2017. 

The CBS All Access show features the franchise's Enterprise, now known as the U.S.S. Discovery. The drama will introduce new characters seeking new worlds and new civilizations while exploring the dramatic contemporary themes that have been a signature of the franchise since its inception in 1966. 

Michelle Yeoh, Anthony Rapp and Doug Jones were announced as the 13-episode series' first castmembers. Chris Obi, Shazad Latif and Mary Chieffo were cast this week as KlingonsStar Trek: Discovery was originally scheduled to debut in January and was pushed back to May, with The Good Wife spinoff The Good Fight now set to be the first scripted offering on CBS All Access, the network's VOD platform.

Star Trek: Discovery hails from Alex Kurtzman, Bryan Fuller and Roddenberry Entertainment. Executive producers include Heather Kadin, Gretchen J. Berg, Aaron Harberts, Akiva Goldsman, Rod Roddenberry and Trevor Roth. Berg and Harberts took over as showrunners for Fuller, who recently noted that he will not be involved in the show's day-to-day after stepping down from his post to focus on Starz's American Gods and other projects.

Martin-Green was cast in The Walking Dead by former showrunner Glen Mazzara after initially auditioning for the role of Michonne that ultimately went to Danai Gurira. Producers created the role of Sasha specifically for her; the character does not exist in the comic book series on which the AMC drama is based. Sasha, as of Sunday's season seven midseason finale, is still alive and serves as Maggie's (Lauren Cohan) confidant at the newly introduced Hilltop community. The character has been a series regular for the past few seasons with Martin-Green appearing on the zombie drama alongside her husband, Kenric Green, who recurs as a member of the Alexandria community. 

Martin-Green's casting brings her back to CBS following a recurring role on The Good Wife. Her credits also include Once Upon a Time.
EW first reported the casting.
