Exciting TV Spinoffs to Anticipate in 2025: 9-1-1, The Big Bang Theory, and More

2025 is shaping up to be a significant year for television spinoffs, with shows like The Handmaid’s Tale, 9-1-1, The Big Bang Theory, and others expanding their universes on screen.

ABC piqued Us‘s interest with the announcement of a second spinoff for 9-1-1. The original series, which debuted on Fox in 2018, centers around first responders in Los Angeles, featuring a main cast that includes Angela Bassett, Peter Krause, Oliver Stark, Jennifer Love Hewitt, Ryan Guzman, Kenneth Choi, and Aisha Hinds.

The first spinoff, 9-1-1: Lone Star, follows a firefighter from New York (played by Rob Lowe) who moves to Texas, wrestling with personal challenges while managing his responsibilities. The ensemble cast also includes Ronen Rubinstein, Sierra McClain, Jim Parrack, Natacha Karam, Brian Michael Smith, Rafael L. Silva, Julian Works, and Gina Torres.

By 2023, 9-1-1: Lone Star secured a fifth and final season on Fox. Eventually, cocreators Ryan Murphy, Brad Falchuk, and Tim Minear shifted their attention toward developing a new spinoff set in a different location.

In October 2024, Murphy shared with Variety, “Tim Minear and I are actively developing a new spinoff that we aim to have on the air by next fall. Unfortunately, while we all adore Lone Star, the financial aspects didn’t align. It’s a Disney operation under a Fox banner, which was never sustainable. We had a great run, though.”

He added, “We’re excited about launching a new series in a yet-to-be-disclosed city, which promises to be a lot of fun. After moving to ABC, 9-1-1 became one of the top shows on Thursday nights. They clearly have an appetite for this kind of content, and we’re eager to deliver another series that I’m truly passionate about.”

Meanwhile, CBS is expanding Fire Country with a spinoff focusing on Morena Baccarin‘s character, Mickey. Titled Sheriff Country, the series will follow Mickey as she combats crime in her modest town while dealing with her ex-con father and a mysterious event involving her rebellious daughter.

“I’m thrilled about this project. Personally, I’m quite proud of what we’ve accomplished thus far,” said Max Thieriot, the lead and creator of Fire Country, regarding the forthcoming CBS show in October 2024. “I only have glimpses of where we are in the discussions for season one, but what I’ve seen so far excites me immensely.”

As an executive producer of Sheriff Country, Thieriot remarked that the show is falling into place, stating, “The enthusiasm in the writers’ room is palpable. When they feel good about the material they’re crafting, it typically translates to quality content. It’s shaping up to be a delightful counterpart to our existing series.”

He concluded with, “Viewers will get a chance to explore a different facet of Edgewater and meet new characters in this community. Delving into the town’s diverse aspects is going to be a lot of fun. It will enrich our understanding of the community and its inhabitants, giving the world a greater sense of completeness.”

Keep reading for a complete lineup of upcoming TV spinoffs we look forward to seeing in 2025:

‘The Testaments’ (Hulu)

Based on Margaret Atwood‘s continuation of the story, Hulu’s The Testaments is set 15 years after the events of The Handmaid’s Tale. Narrated by Aunt Lydia, played by Ann Dowd, the series follows three women as they recount the happenings in Gilead after June (Elisabeth Moss) was captured, and Aunt Lydia was exposed as a Mayday mole. Their mission is to secretly gather and transport damning evidence about Gilead’s oppressive regime abroad to aid in its downfall.

The objective is to air The Testaments following the conclusion of The Handmaid’s Tale‘s final season in 2025.

‘The Madison’ (Paramount Network)

Before the conclusion of Yellowstone in December 2024, ViacomCBS president Chris McCarthy informed The Hollywood Reporter of a spinoff featuring Matthew McConaughey. However, a year later, that spinoff seemed to have fizzled out and gave way to a new project titled The Madison.

Michelle Pfeiffer will star in this new series, alongside Patrick J. Adams, Kurt Russell, and Beau Garrett. The Madison marks the inaugural spinoff within the Yellowstone universe set in the present.

Untitled ‘9-1-1’ Spinoff (ABC)

9-1-1 first premiered on Fox in 2018 before making the jump to ABC, introducing audiences to the personal and professional lives of Los Angeles emergency responders. Currently in development, the details about the setting for the new iteration remain unclear. Reports have indicated that ABC plans to launch the second 9-1-1 spinoff, following Fox’s 9-1-1: Lone Star, during the 2025-26 TV season, specifically in the fall of 2025.

‘Sheriff Country’ (CBS)

Fire Country, which made its debut in 2022, chronicles the story of inmate Bode (Thieriot) who volunteers for the California Conservation Camp Program back in his hometown of Edgewater. Season 2 broadened this narrative with a backdoor pilot that highlighted the law enforcement side.

Sheriff Country focuses on Sharon’s (Diane Farr) estranged sister, Mickey (Baccarin) as she tackles crime in Edgewater. CBS approved the spinoff in May 2024, but the series is anticipated to air in the 2025-2026 season.

Untitled ‘The Big Bang Theory’ Spinoff (Max)

The Big Bang Theory ran from 2007 to 2019, introducing viewers to a group of scientists and their significant others, including Us stars Jim Parsons, Kaley Cuoco, Johnny Galecki, Simon Helberg, Kunal Nayyar, Mayim Bialik, and Melissa Rauch. Following the end of the sitcom, CBS launched a prequel focusing on Parson’s character Sheldon, titled Young Sheldon, which later paved the way for another show about Sheldon’s older brother, namely Georgie & Mandy’s First Marriage.

An untitled spinoff is currently in development at Max, featuring Brian Posehn, Lauren Lapkus, and Kevin Sussman, who will headline the series after portraying side characters in later seasons of The Big Bang Theory. No release date has been confirmed as production progresses on this follow-up.

‘It: Welcome To Derry’ (Max)

The Welcome to Derry series explores the origins of Stephen King‘s infamous killer clown, Pennywise. Bill Skarsgård, who serves as an executive producer for the project, will reprise his role as Pennywise, having originally portrayed the character in the latest film reboot.

Untitled ‘Stranger Things’ Spinoff (Netflix)

Creators Ross and Matt Duffer revealed that the fifth and final season of Stranger Things wouldn’t entirely mark the end of the franchise. While no plot details have been disclosed yet, the new series will likely exist within the same universe, considering that the original show hinted at further stories involving Hawkins Lab test subjects during season 2.

Untitled ‘Reacher’ Spinoff (Prime Video)

Based on the Jack Reacher book series authored by Lee Child, Reacher showcases Alan Ritchson as a self-described “hobo” and former U.S. Army military policeman, employing his intellect and skills to confront dangerous criminals.

The Reacher universe is set to expand with a spinoff featuring Maria Sten‘s character, Frances Neagley.

‘Vision Quest’ (Disney+)

The success of WandaVision initially led to the Agatha All Along spinoff before Paul Bettany secured a series centered around Vision. Slated to start filming in 2025, the upcoming show aims to cap off a trilogy focusing on Elizabeth Olsen‘s character Wanda and Bettany’s Vision.

‘Boston Blue’ (CBS)

In Boston Blue, Donnie Wahlberg reprises his role as NYPD officer Danny Reagan, who transitions to the Boston police force. When he arrives, he partners with detective Lena Peters, the eldest daughter from a notable law enforcement family.
