There’s good news and bad on the front of CBS’ Star Trek: Discovery, which is starting to sound like an old refrain. And speaking of frains, James Frain has been added to the cast in the role of Spock’s father Sarek, albeit at the cost of an official May premiere. So, when should we expect the series?

Per Entertainment Weekly, the Orphan Black star will play a younger version of Sarek, described as a “key character” in the Discovery story, which takes places a decade before the original Star Trek. That said, while the series begins production in Toronto next week, CBS has opted to push the premiere, potentially as far back as fall.

Why, you ask, after already pushing the premiere out of January to accommodate Bryan Fuller’s vision? Not so dissimilar reasons:

This switch has a few reasons behind it, a key one is that recently cast star Sonequa Martin-Green is on AMC’s mega-hit The Walking Dead, which is airing its current season through April. There’s a concern about marketplace confusion if CBS were to ramp up promoting her as the star of a new sci-fi show while her horror hit is currently on the air. The other reason is there’s still a lot of careful deliberation continuing to go into making Discovery special, from the choice of directors, to set design, to the special effects. While May would have been a strong premiere month for the project since Discovery will premiere on the CBS broadcast network before moving to the streaming service (May is a ratings surge month), given that Discovery will live on All-Access there’s no pressure to fill a specific time slot.

Previously, Star Trek: Discovery confirmed among the cast Sonequa Martin-Green as our Lt. Commander lead, Doug Jones as an alien science officer, Adam Rapp as the TV franchise’s first openly-gay character and Michelle Yeoh as Captain of a different ship, along with several Klingon roles. Ex-showrunner Bryan Fuller also recently stepped up to clarify his limited involvement in the project going forward.

Shooting in Toronto, the new 13-episode Star Trek: Discovery is officially said to take place 10 years before Kirk’s original Enterprise mission, as well to be “heavily serialized,” akin to a novel. The new series will also explore the fallout of an event referenced, but never seen in the original series.

Wrath of Khan director Nicholas Meyer has also joined alongside Gene Roddenberry’s son Rod, fan-favorite Voyager novel alum Kirsten Beyer, franchise vet Joe Menosky and Heroes writer Aron Coleite.

Better that Star Trek: Discovery take the time to get things right, but what make we of Spock’s father taking a central role?
