Doug Jones (The Strain) and Rent alum Anthony Rapp have been cast in Star Trek: Discovery, the upcoming new Star Trek series for CBS All Access, CBS’ live streaming and VOD service, and Michelle Yeoh is confirmed for her role as a Starfleet captain.

Jones will portray Lt. Saru, a Starfleet Science Officer and a new alien species to the Star Trek universe. Rapp will play Lt. Stamets, an astromycologist, fungus expert, and Starfleet Science Officer aboard the Starship Discovery. And as Deadline previously reported, Yeoh will play Captain Georgiou, the Starfleet Captain aboard the Starship Shenzhou. The series does not yet have the lead, but is getting close to casting her.

Star Trek: Discovery will feature a new ship, new characters, and new missions, while embracing the same ideology and hope for the future that inspired a generation of dreamers and doers. The series premieres May 2017 on the CBS network with all subsequent episodes available in the U.S. on CBS All Access. The series will be distributed concurrently by CBS Studios International on Netflix in 188 countries and in Canada on Bell Media’s Space Channel and CraveTV.

The series is produced by CBS Television Studios in association with Alex Kurtzman’s Secret Hideout, Bryan Fuller’s Living Dead Guy Productions and Roddenberry Entertainment. Alex Kurtzman, Bryan Fuller, Heather Kadin, Gretchen J. Berg & Aaron Harberts, Rod Roddenberry and Trevor Roth will serve as executive producers.
