The new actors join a cast that includes “The Walking Dead” actress Sonequa Martin-Green, who will star as the lead lieutenant commander, plus James Frain as Spock’s father Sarek, Anthony Rapp as a space fungus expert, and Michelle Yeoh as the captain in charge of the Starship Shenzhou. Other cast members include: Jason Isaacs as the captain of the Discovery; Terry Serpico as Admiral Anderson, a high-ranking official of Starfleet; Maulik Pancholy as Dr. Nambue, the chief medical officer of the Starship Shenzhou; Sam Vartholomeos as Ensign Connor, a junior officer in Starfleet Academy assigned to the Starship Shenzhou; and “The Office” alum Rainn Wilson in the role of Harry Mudd.

The embattled and oft-delayed relaunch of the “Star Trek” television franchise is currently slated to premiere in “late summer, early fall,” CBS Corp. chief executive Leslie Moonves told an investor conference in February. The series had been originally slated to premiere in January, but production delays and the dismissal of former showrunner Brryan Fuller, still an executive producer on the project, have set the show back.
