Reacher season 4: everything we know so far about the hit Prime Video show’s return

Reacher season 4 is officially filming. No surprise given season 4 was officially renewed back in October 2024. But, very welcome news nonetheless. And boy, do we have a lot to talk about.

Finding it's home on Prime Video, one of the best streaming services, Reacher has been a standout hit from the very beginning. And now, three seasons deep, we're excited to hear that one of the best Prime Video shows is gearing up for its big return.

Based on the novels by Lee Child, action-packed thriller follows Jack Reacher, an ex-military police officer, who finds himself continuously embroiled in conspiracies and dangerous missions after being wrongly accused of murder. And with 29 books published (and counting), there's plenty more Reacher action to unleash.

A tumultuous season 3 ending hints at more full throttle fights and government conspiracies, so here's everything we know about Reacher season 4 from a release date, to confirmed cast, plot rumors, trailer and more.

Full spoilers follow for Reacher season 3 and the previous seasons. Plus, spoilers for Reacher season 4 will also appear.

Reacher season 4 release date prediction

There’s no Reacher season 4 release date just yet, but we do know that the show was renewed back in October 2024.

Speaking to The Mirror in February, Child said: “So we’re ready to go on season four. Obviously, we can’t reveal anything yet, but it’s another good’un, I’ll tell you. It’s going to be great.” He added: “I’ll see you next year and we’ll talk about it,” possibly hinting that Reacher season 4 will premiere in 2026.

If we take previous seasons as a guide for season 4, season 1 came out in 2022, season 2 ran from 2023 to 2024, and season 3 in 2025. If Prime Video continues releasing annually, it could well be early 2026.

When Child discussed future seasons of Reacher in an exclusive chat with TechRadar, he revealed filming will commence sooner than you might think: “It’s written and it’s ready to go. It’s going to start shooting in the summer.”

And it appears the Reacher cast and crew have commenced filming with an official Instagram post from Alan Ritchson posting photos from set as surprise guest Joe Biden as his family dropped by.

Reacher season 4 trailer: is there one?

Given the cast and crew only commenced filming in June, there’s no trailer to share. Historically, trailers come out a lot nearer to the release of the show. So, for a Reacher season 4 trailer, we imagine a wait until at least late 2025, early 2026.

Reacher season 4 confirmed cast

Full spoilers follow for Reacher season 3.

Here are the Reacher season 4 cast that have been revealed so far, including main characters and guest stars:

• Alan Ritchson as Jack Reacher
• Maria Sten as Frances Neagley
• Christopher Rodriguez-Marquette as Jacob Merrick
• Sydelle Noel as Tamara Green
• Agnez Mo as Lila Hoth
• Anggun as Amisha Hoth
• Kevin Weisman as Russell Plum
• Marc Blucas as John Samson
• Kevin Corrigan as Detective Docherty
• Kathleen Robertson as Elsbeth Samson

Given that the main characters that appears alongside Reacher each season tend to change given he moves onto a whole new story, Neagley has shown up in every season so far. So, I'd expect we'll see her again.

And while Christopher Rodriguez-Marquette has been cast to play Jacob Merrick, that wasn't always the case. Variety reported the casting announcement for the eight new roles on June 13 with Jay Baruchel as Jacob.

On June 26 though, Deadline followed up with news of a recasting as Baruchel was "forced to exit the series to attend to a personal matter".

Reacher season 4 plot details & rumors

Full spoilers follow for Reacher seasons 1 to 3. Potential spoilers also follow for Reacher season 4.

Jack Reacher is a man on a mission, or several missions actually if you take all seasons so far into consideration. Over three seasons so far, he’s been repeatedly ensnared in conspiracies that put a lot of lives at risk, including his own.

From false murder accusations to going deep undercover to retrieving a lost DEA agent, following Lee Child's novels has given plenty of plot for the show to follow along with.

And season 3 saw Reacher’s feud with villains (new and old), Xavier Quinn and Zachary Beck, come to a head. The finale episode, titled ‘Unfinished Business’, saw Reacher's team break down a crime syndicate, run by Beck, by infiltrating his base. But, in order to do so, he had to come up against Beck's towering bodyguard, Paulie. And that led to an almighty fight placing brains against brawn.

At the end of it all, he sat down with Neagley and talked about the real reason Reacher gets embroiled in so much trouble, because he hates the "big guy".

While Reacher season 1 was adapted from Killing Floor, Child’s debut novel, season 2 from Bad Luck and Trouble, his 11th novel, and season 3 from Persuader, his 7th novel, it's clear they're not going in book order, but they're certainly going from the books.

And Reacher season 4 will follow Child's 13th book, Gone Tomorrow. If you've read the book, you'll know what's coming. But, without giving too much away, the official announcement gives us some insight into what season 4 will be like.

Gone Tomorrow opens on a New York City subway train, which was previously hinted at in Alan Ritchson's Instagram post of the season 4 script laying on a subway seat (featured above) before official confirmation.

And in the Instagram post that confirmed it all, Ritchson included the quote: "The thing about subway cars is you step on one and you never know what's going to happen". And that's exactly what's about to unfold.

In Gone Tomorrow, Reacher has an encounter with a stranger that goes incredibly wrong. Suspecting her to be a suicide bomber, she ends up shooting herself unexpectedly as he approaches.

Afterwards, Reacher wants to find out who she was and why it happened. And, in true Reacher fashion, the truth takes him deeper into government deception and conspiracy than he ever thought possible.

Speaking to The Independent Child supports that the show can jump around the book order, saying he: “very deliberately wrote the book series so you did not have any prior knowledge". Adding: "I wanted people to be able to pick up any title anywhere and have a really satisfying story, so we can take the same approach.”

Where to watch Reacher

Reacher seasons 1 to 3 can be streamed exclusively on Prime Video. Finished them all and eager for more? Check out these 6 muscular thrillers to watch while you wait.

Will there be more seasons of Reacher?

It's incredibly likely. Reacher season 4 was greenlit months before season 3 came out, and we wouldn't be surprised to hear about season 5 in a similar way. And, of course, there's all the books that Lee Child has written of the Jack Reacher series — currently totalling 29.

But, it's not just Reacher that'll be on the scene. In October 2024, Prime Video announced spin-off series, Neagley, focused on none other than Frances Neagley (Maria Sten).

And in June, as Reacher season 4 filming commenced, Maria Sten posted that filming on Negaley had officially wrapped. She added: "I hope you're ready cause it's gonna be a wild one!"

Of course this isn't confirmation for more of the main Reacher show, but it's certainly the start of a new, no doubt adrenaline-filled, path.
