Alan Ritchson, the larger-than-life star of Prime Video’s Reacher, just got fans hyped with a sneak peek at Season 4. On May 21, 2025, the 42-year-old, who plays the badass drifter Jack Reacher, shared a bunch of behind-the-scenes pics on Instagram, calling it “the most intensely physical season yet.” With filming set to start this summer, Ritchson’s post has everyone buzzing about what’s next for the action-packed show.
His Instagram carousel is a goldmine. One shot shows Ritchson stretching with stunt coordinators Buster and Eric, hinting at the bone-crunching fights fans can’t get enough of. Another has him in a costume fitting, rocking Reacher’s classic rugged vibe. The real treat? A snap with Lee Child, the guy behind the Jack Reacher books, who’s a big part of the show’s DNA. Ritchson’s caption, “My body is ready,” promises he’s gearing up for a brutal season, and he even teased, “I dare say this might be the best season of the series.” That’s big talk after Season 3’s perfect 100% on Rotten Tomatoes.
Reacher, based on Child’s bestselling novels, follows Jack Reacher as he wanders the U.S., taking down bad guys with his smarts and fists. Season 3, which wrapped on March 27, 2025, tackled Persuader, with Reacher going undercover to bust a drug ring. Prime Video was so confident in the show’s pull that they greenlit Season 4 back in October 2024, before Season 3 even hit screens. Amazon’s Vernon Sanders called Reacher a “phenomenon,” and it’s easy to see why—it’s a global hit.
No word yet on which book Season 4 will adapt, but Ritchson’s dropped hints about loving Die Trying (1998), where Reacher gets kidnapped in Chicago and takes on a militia. He told SlashFilm it suits Reacher’s lone-wolf style, saying he’s “drug reluctantly into the situation.” Nothing’s confirmed, but with Child saying scripts are locked and filming starts after summer, fans are already guessing.
The photos also give a shout-out to the Neagley spin-off, starring Maria Sten as Reacher’s tough-as-nails pal Frances Neagley. Ritchson’s set to pop up in it, and one pic shows him hanging with Sten and the Neagley crew, hinting at some crossover vibes. Since Neagley’s filming (February to June 2025) shares crew with Reacher, Season 4’s production is likely kicking off late summer, meaning we might not see it until early 2027.
Ritchson’s no stranger to pushing his limits. He read all 24 Reacher novels to nail the role and packed on 30 pounds for Season 1, even through injuries like a busted shoulder and torn oblique. Variety noted he needed surgery after Season 1’s stunts, and for Season 3, he got knocked out filming a finale brawl with 7’2” giant Olivier Richters. Yet, his Instagram post is all energy, showing him pumped for the grind.
Fans are stoked. Reacher’s mix of gritty action, clever mysteries, and Reacher’s dry humor has made it a Prime Video juggernaut. Season 2 was the platform’s most-watched show in 2023, and Season 3’s critical slam dunk has raised the stakes even higher. Ritchson told The Hollywood Reporter that the show clicks because it’s got something for everyone—ladies love the fights, guys dig the brainy puzzles. His behind-the-scenes drop only cranks up the excitement, promising more of that Reacher magic we can’t get enough of.
With filming around the corner and Ritchson hyping a season that could top them all, Reacher Season 4 is shaping up to be a wild ride. For now, you can binge Seasons 1-3 on Prime Video and keep an eye out for more updates as production heats up. Get ready—Reacher’s coming back, and he’s bringing the pain.
