The first is Chris Obi (Roots) as T’Kuvma, a leader seeking to unite the Klingon houses.

The second is Shazad Latif (Penny Dreadful) who will play Kol, a Klingon Commanding Officer, and protege of T’Kuvma.

And the third is newcomer Mary Chieffo as L’Rell, the Battle Deck Commander of a Klingon ship.

The trio join three previously announced actors including Michelle Yeoh, who will play Captain Georgiou, the Starfleet Captain aboard the Starship Shenzhou; Doug Jones (Hellboy, Falling Skies) as play Lt. Saru, a Starfleet Science Officer and a new alien species in the Star Trek universe; and Anthony Rapp (Rent, Road Trip) as Lt. Stamets, an ” astromycologist,” fungus expert, and Starfleet Science Officer aboard the Starship Discovery.

The show’s lead character, a female lieutenant aboard the Discovery, has not yet been cast.

Star Trek: Discovery will launch May, 2017 on CBS All Access.
