Star Trek: Discovery has cast The Walking Dead actress Sonequa Martin-Green in the show's lead role of Lt. Commander Rainsford, according to Deadline. Martin-Green will reportedly continue to act on The Walking Dead concurrently with Star Trek: Discovery.
Little is known about Martin-Green's character, however former Star Trek: Beyond showrunner Brian Fuller described her as a "sensitive hero," and wrote the part with a non-white woman in mind.
Star Trek: Discovery is scheduled to premiere on CBS in May 2017 before moving to the network's proprietary streaming service CBS All Access.
