If you've been waiting patiently for CBS to release its new Star Trek series, prepare to keep waiting. According to The Hollywood Reporter, Star Trek: Discovery has been delayed indefinitely while CBS gives the "ambitious project" more time to incubate.

"We've said from the beginning it's more important to do this right than to do it fast," CBS said in a statement. "There is also added flexibility presenting on CBS All Access, which isn't beholden to seasonal premieres or launch windows."

The Reporter also says that James Frain (Orphan Black, Gotham, Tron: Legacy, and more) has been cast as Spock's father, Sarek, and that the series is set to begin production "next week."

The announcement is the most recent sign of trouble for the latest iteration of Star Trek. Showrunner Bryan Fuller left the project in October of 2016 because he was too busy with his other obligations, leaving the show in the hands of Gretchen Berg and Aaron Harberts (both worked with Fuller on Pushing Daisies in the late 2000s). At the same time, Discovery was delayed from its original January 2017 debut to May 2017. CBS' decision to run the show exclusively on its $5.99-a-month All Access streaming service, rather than on live TV or on a generalized service like Hulu, has also sparked controversy.

Discovery, the first Trek TV series since Enterprise was canceled in 2005, is set in the Original Series era a decade before Kirk, Spock, and McCoy's five-year mission. It's set to take place in the so-called "Prime" timeline of TOS, The Next Generation, Deep Space Nine, and Voyager, and not the new "Kelvin" timeline established by the 2009 film reboot. It will be the first Trek series since DS9's early seasons not to focus on the captain as the main character, and the first since Voyager with a female lead.
