While confirming that Michelle Yeoh is indeed a part of Star Trek: Discovery's cast, CBS has also announced that Doug Jones and Anthony Rapp have signed aboard. The series' lead, Number One, is a role that an announcement is expected on shortly.
Jones, not surprisingly given his many creature credits, is playing a member of a previously unseen alien species, Lt. Saru, who serves aboard the starship as a Starfleet science officer. Rapp (A Beautiful Mind), is also a science officer as well as astromycologist and fungus expert (!) named Lt. Stamets. As previously reported, Yeoh will be portraying Captain Han Bo of the U.S.S. Shenzhou.
Every Star Trek series has had its share of growing pains from conception through production, and Discovery is no different. Bryan Fuller had originaly been made showrunner alongside Alex Kurtzman, but recently left the project due to an overwhelming workload that includes Starz' forthcoming adaptation of American Gods. Now guiding the show are Gretchen J. Berg and Aaron Harberts, with a staff that includes Nicholas Meyer, Jesse Alexander and Joe Menosky.
