Deadline TV: Karla Souza Will Lead ABC's New Grey's Anatomy Spinoff

Karla Souza has been cast as a lead in ABC's new Grey's Anatomy spinoff, Deadline reported on Wednesday, November 11. The outlet said she is the first actor to join the untitled series, which is set in West Texas and produced by 20th Television.

The news gives the long running medical franchise its first confirmed face for a new chapter, and it reunites Souza with the producers behind one of her best known roles.

A Doctor at the Edge of Nowhere

According to Deadline, the series was created by Grey's Anatomy creator Shonda Rhimes and current showrunner Meg Marinis. It is described as an edgy drama about a team at a rural West Texas medical center that serves as the last chance for care before miles of empty country.

Souza will play Carolina "Lina" Hall, described by Deadline as a haunted and cynical doctor in her 40s who runs the medical center in a small town. Rhimes, Betsy Beers, Marinis and Ellen Pompeo are executive producers.

Marinis has run the flagship series in recent seasons, so the new show arrives with the franchise's current creative leadership attached from the start rather than handed to an outside team.

The premise moves the franchise far from the big city hospital world of Seattle that defined the original series. A small town clinic with limited resources offers a different kind of pressure, and the character description suggests a lead with a past that the show intends to explore.

A Reunion With Shondaland

For Souza, the role is a homecoming of sorts. She played Laurel Castillo opposite Viola Davis in ABC's How to Get Away with Murder, which Rhimes and Beers executive produced through Shondaland. That series made her a familiar face to network audiences.

Deadline noted her more recent work as well. She was a series regular in Prime Video's 56 Days opposite Dove Cameron and Avan Jogia, played Marina on ABC's Home Economics and appeared opposite Jamie Foxx in Netflix's Day Shift. She also received two International Emmy Awards for producing and starring in Dive, known in Spanish as La Caída, for Prime Video.

Leaving Los Angeles Behind

The production story is almost as notable as the casting. Deadline reported last week that the spinoff will be the first series in the franchise's 23 year history to shoot outside Los Angeles. After it was unable to secure a California tax credit, the outlet said, the show is now based in Albuquerque, New Mexico.

Shondaland has long filmed in California, including for Grey's Anatomy, Private Practice and Station 19, even when the stories were set elsewhere. New Mexico has spent years courting film and television work with its own incentive program, and Albuquerque has become a familiar base for productions that once would have stayed in Southern California.

Moving a flagship franchise out of state is a clear sign of how much production incentives now shape where television gets made.

What Is Confirmed and What Comes Next

The confirmed facts are straightforward: Souza is cast as a lead, the character is Lina Hall and the show is set in West Texas. Citing sources, Deadline said production is expected to begin in early 2027, around February or March, with a premiere planned for the 2027 to 2028 season.

Casting a lead first is a common step for a new network drama. It gives writers a performer to shape the character around and gives the network a name to build early publicity on while the rest of the ensemble is assembled.

Much remains unannounced, including the title, the rest of the cast and any links to existing Grey's Anatomy characters. ABC has not shared those details. Fans of the original will be watching closely to see whether familiar names cross over, but for now the story centers on a new doctor, a new town and a familiar actor taking charge.
