Who Are the Star Trek Discovery Cast Members?
Here is a current run-down of the full Star Trek Discovery cast as of April 30th, 2017.

Sonequa Martin-Green
Sonequa Martin-Green will be playing the series lead character, Lieutenant Commander Michael Burnham (AKA “Number One”), USS Discovery’s First Officer. In addition to being part of the Star Trek Discovery cast, Sonequa is also currently in AMC’s The Walking Dead where she is a repeating character. No official announcement has been made on CBS’ Star Trek Discovery casting page, however StarTrek.com itself has confirmed Sonequa’s casting on their website, so the announcement is official. It’s unclear why CBS’ page makes no mention.

Doug Jones
Doug Jones is slated to be part of Star Trek Discovery‘s cast playing an alien species never before shown in the Trek universe. This is in fitting with Jones’ previous roles. He’s often featured in the science fiction, fantasy, and horror genres. He’s often wearing heavy makeup to play nonhuman characters. We suspect he may be doing the same on Discovery.

Anthony Rapp
Anthony Rapp is probably best known for his role in Road Trip, where he played a university professor’s creepy Teaching Assistant. Rapp was cast to Star Trek Discovery to play the roll of Lieutenant Stamets, Star Trek‘s first openly gay character on any series. He is also a stage actor best known for his role of Mark Cohen in the Broadway production Rent, and for the film version.

Chris Obi
Obi has already had a busy 2017. In addition to Discovery, he also has prominent roles in American Gods and on the upcoming feature film Ghost in the Shell. He was also in 2012’s Snow White and the Huntsmen.
Obi will be playing T’Kuvma, leader of the Klingon Empire.

He can also be seen in The OA, another Netflix original series. Isaacs has had an illustrious career spanning three decades of film and television.
“Trekkie fans are desperate for any kind of homeopathic hint of what’s going on. I can tell you that it’s called ‘Star Trek Discovery’; I can tell you I’m in it and I have started shooting. It is absurdly cool, I feel like a five year old. Anything else I tell you would just ruin it for you.”

Mary Wiseman
Mary Wiseman will be playing Cadet Tilly in Star Trek Discovery. Wiseman is a relative newcomer and is best known for her role in Longmire.

History of Star Trek Discovery Casting
Note: italicized items are rumors or speculation
In June 2016, Bryan Fuller, talking about casting for Star Trek Discovery, said he had “met with a few actors, and it’s an interesting process. There’s a few people that we like and we want to carry on what Star Trek does best, which is being progressive. So it’s fascinating to look at all of these roles through a colorblind prism and a gender-blind prism”.
Update (January 18, 2017): James Frain has been added to the cast. Frain will be portraying Sarek, Spock’s father.
Update (December 14, 2016): News that Star Trek Discovery has finally cast its leading role. Sonequa Martin-Green has been brought on to play Lieutenant Commander Rainsford (aka Number One). The addition comes just days after the last casting announcement of three Klingons.
Update (December 12, 2016): Things just keep on heating up on the Discovery casting front. Today, CBS announced three additional cast members of Star Trek Discovery. All three are slated to play Klingons. Today’s announcement featured Chris Obi, Shazad Latif and Mary Chieffo. It’s unclear if the Klingons will be presented with ribbed foreheads, or if they’ll look more human, like the Klingons shown in Star Trek: The Original Series.
Update (November 29th 2016): Things are starting to heat up. Over the past few days, rumors have surfaced about a few actors that will join the Starfleet ranks. Today, CBS officially announced three actors to appear in Star Trek Discovery‘s cast. Michelle Yeoh, Anthony Rapp, and Doug Jones have been confirmed to appear in the show.
Update (August 29th 2016): We probably shouldn’t expect to learn about actors in Star Trek: Discovery for another month or more. According to KERN-FM’s Nerd World Report, Bryan Fuller is reported as saying that “we’ll probably have some announcements in October. We’ve met with fantastic actors and of course there are people I’ve worked with before that I’d love to see on Star Trek. We’re trying to figure out everybody’s schedules.”
To get an idea of what Fuller may be looking for, a few years ago he stated he’d love to head up a new Star Trek series, casting Angela Bassett as the captain with Rosario Dawson as ship’s commander. It’s unlikely we’ll see either of these two talented ladies as primaries in the show, but it bodes well for keeping in line with Trek’s stance on race and gender.

Star Trek Discovery Cast Diversity
Speaking of gender, both Bryan Fuller and Heather Kadin have eluded to the possibility that there may be one or more LGBTQ members of the Star Trek Discovery cast (confirmed)- at long last. Heather was quoting as saying “[it] is something that’s very important to Bryan, and very important to all of us to portray.” Heather is also quoted as saying “on one hand, I think Gene Roddenberry’s original vision reflected what the world looked like more than what a lot of television does today”, primarily referring to minority representation. So it’s sounding more and more like Star Trek Discovery cast will be a true “Team United Nations” – or should we say “Team United Federation of Planets”.
Personally, I feel that Indians (those from India as opposed to aboriginal “Indians” to my American friends), Pakistani, and Chinese are way under-represented in Star Trek. I’d like to see both in the Star Trek Discovery cast in major roles.
Stay tuned and we’ll bring you the latest on the Star Trek Discovery cast as its announced.
