The Walking Dead star, Sonequa Martin-Green has been cast in the lead role for Star Trek: Discovery. 

Variety are reporting that Martin-Green, who plays Sasha Williams in the AMC zombie drama will play the lead role but will not be the ship's captain as has previously been the tradition in Star Trek television shows. Her character will hold the rank of lieutenant-commander, though the character’s name is still unknown.

Martin-Green joins the previously announced cast list which includes Doug Jones, Anthony Rapp, Michelle Yeoh, Chris Obi, Shazad Latif, and Mary Chieffo. 

In case you were wondering if this means that her Walking Dead character is now going to be killed off, the report from Variety claims that she will still be a series regular on the show while also fulfilling her Star Trek commitments. 

Although one would have to suspect that her role on the Walking Dead will have to become a little bit smaller for her to be able to manage both.
