How good do you have to be to fight in the zombie apocalypse and travel through space at the same time? Sonequa Martin-Green is going to try. She plays Sasha on "The Walking Dead" but Entertainment Weekly just revealed she has been cast in the lead role of the CBS All Access series "Star Trek: Discovery," playing lieutenant commander of the Discovery.

"The Walking Dead" finished filming Season 7 in November, but it should pick back up in May and film Season 8 in Georgia until next November. Meanwhile, Collider said "Discovery" will shoot in Toronto. There definitely seems to be some time from November to May when Martin-Green could fit in "Star Trek" filming, but she's meant to be the lead character of this series, and every time a new TWD star gets a lead role somewhere else, it means their character is leaving the AMC show.

However, EW reported that "Martin-Green will continue to serve as a series regular on AMC's zombie drama, where she has played the tough pragmatic survivor Sasha Williams since Season 3." But the PR folks have to tell them that. It's not like they could tell the site, "Yeah, she's leaving TWD. Sasha is toast."

The CBS All Access show's original showrunner Bryan Fuller told EW that Martin-Green's character is a "lieutenant commander with caveats." He explained, "We've seen six series from the captain's point of view. To see a character from a [new] perspective on the starship — one who has different dynamic relationships with a captain, with subordinates, it gave us richer context."

"Star Trek: Discovery" premieres in May.
