CBS All Access' Star Trek series headed by Patrick Stewart continues to fill out its cast.

Alison Pill (The Newsroom), Harry Treadaway (Penny Dreadful) and Isa Briones (Hamilton) have come aboard the show as series regulars. They join Santiago Cabrera, Michelle Hurd and Evan Evagora in the cast.

Details about their roles are being kept quiet for the time being.

The untitled series will focus on Stewart's Jean-Luc Picard as he enters the next chapter of his life. Stewart is reprising the role for the first time since the 2002 film Star Trek: Nemesis

Executive producer Alex Kurtzman told The Hollywood Reporter in January that the show will find Picard's life "radically altered" after the dissolution of the Romulan Empire. At PaleyFest in March, he also said that the show will have a much different tone than CBS All Access' Star Trek: Discovery, which is set before the events of the original Star Trek series.

"The only way this show works correctly is if it's different from Discovery," Kurtzman said.

The Picard series is one of several Star Trek projects in the works at CBS All Access. In addition to Discovery and spinoff Short Treks, the streaming service has given a two-season order to animated series Lower Decks and is developing a Discovery spinoff starring Michelle Yeoh, a second animated series and a Starfleet Academy project. Another animated Trek series aimed at kids is in the works at Nickelodeon. 

Kurtzman and Stewart are executive producers of the Picard series along with James Duff, Akiva Goldsman, Michael Chabon, Heather Kadin, Rod Roddenberry and Trevor Roth. Aaron Baiers of Kurtzman's company Secret Hideout is a co-exec producer. 

Pill is coming off work on FX's series Devs. Her recent credits include Vice and American Horror Story: Cult. She is repped by CAA and The Burstein Company.

Treadaway starred for two seasons on DirecTV's Mr. Mercedes and recently wrapped filming on season four of Netflix's The Crown. He is repped by Principal Entertainment LA.

Briones was part of the first national touring company of Hamilton and had a guest role on American Crime Story: Versace. She is repped by Piper/Kaniecki/Marks Management
