The Captain of the U.S.S. Discovery is now reporting for duty!

Actor Jason Isaacs has been cast as Captain Lorca in Star Trek: Discovery, launching exclusively on CBS All Access.

Additionally, Mary Wiseman (Baskets) has joined the cast as Cadet Tilly, a Starfleet Academy Cadet in her final year of study, also assigned to the Discovery.

The actors join previously announced stars Terry Serpico, Maulik Pancholy, Sam Vartholomeos, James Frain, Doug Jones, Michelle Yeoh, Anthony Rapp, Chris Obi, Shazad Latif, and Mary Chieffo.


Set roughly ten years before the events of The Original Star Trek, the series follows the crew of the USS Discovery as they discover new worlds and civilizations, while exploring the franchise's signature contemporary themes. The season-long storyline revolves around "an incident and an event in Star Trek history that's been talked about but never been explored".



Cast and characters

  • Sonequa Martin-Green as Rainsford: A lieutenant commander assigned to the USS Discovery, referred to as "Number One". The decision to not make the series' protagonist a starship captain, like those of previous Star Trek series, was made "to see a character from a different perspective on the starship—one who has different dynamic relationships with a captain, with subordinates, it gave us richer context". The decision to call her Number One was made in honor of the character of the same name portrayed by Majel Barrett in the original Star Trek pilot "The Cage". The character was initially pitched to CBS as only being called Number One in the series.

  • Terry Serpico as Anderson: A Starfleet admiral.

  • Maulik Pancholy as Nambue: Chief Medical Officer of the USS Shenzhou.

  • Sam Vartholomeos as Connor: A junior officer in Starfleet Academy, assigned to the Shenzhou.

  • James Frain as Sarek: A Vulcan astrophysicist, and the father of Spock. Frain appears as a younger version of the character who was first portrayed by Mark Lenard in the original Star Trek series.

  • Doug Jones as Saru: A Science Officer serving as a lieutenant aboard the Discovery. Jones, portraying a member of a species created for the series, was excited that he was able to, "from the ground up, develop and find this character and his species" and not have to honor a previous fan-favorite representation.

  • Michelle Yeoh as Georgiou: Captain of the Shenzhou.

  • Anthony Rapp as Stamets: A Science Officer specializing in astromycology (the study of fungi in space).

  • Chris Obi as T'Kuvma: A Klingon leader who is looking to unite the Klingon houses.

  • Shazad Latif as Kol: Commanding Officer of the Klingons, and protege of T'Kuvma.

  • Mary Chieffo as L'Rell: Battle Deck Commander of the Klingon ship.

  • Jason Isaacs as Lorca: Captain of the Discovery.

  • Mary Wiseman as Tilly: A cadet in her final year at Starfleet Academy, assigned to the Discovery.
