Jensen Ackles to Star in MGM+ ‘Rules of Prey’ Thriller Series

Jensen Ackles is set to headline and executive produce Rules of Prey, an eight-episode crime thriller ordered by MGM+ and adapted from the first novel in John Sandford’s long-running Prey series, Deadline reported exclusively on Tuesday. The series follows Lucas Davenport, a former Minneapolis Police Department detective drawn out of seclusion to investigate murders designed to send a message specifically to him, sparking a psychological duel with a killer who treats their conflict as a game.

Variety confirmed the greenlight and said production begins this month in Toronto, with a premiere planned for MGM+ in the United States plus the United Kingdom, Ireland, Germany, Spain, Italy, Belgium, Brazil, Mexico, Argentina, and Chile. Bruce Terris, the Emmy-winning executive producer of DTF St. Louis, created the series and will serve as showrunner and executive producer under his overall deal at MGM Television. Daniel Sackheim, whose directing credits include Game of Thrones and True Detective, will helm the first two episodes and executive produce.

Deadline’s logline frames Davenport as a brilliant polymath and unconventional investigator whose sharp mind and unwillingness to let procedure block justice once forced him out of the Minneapolis force. When an ingenious serial killer begins murdering citizens across the city, Davenport must decipher a twisted moral code and personal vendetta while matching wits with a predator operating by private rules. That cat-and-mouse structure is the DNA of Sandford’s 1989 debut novel—published under the pseudonym of Pulitzer-winning journalist John Camp—and of a franchise that has since stretched to more than three dozen Prey books, including 2026’s Revenge Prey.

Michael Wright, global head of MGM+, called Ackles’ “classic leading man charisma” and Terris’ adaptation of Sandford’s “enduringly popular” novels an excellent fit for the streamer’s commitment to classic Hollywood storytelling for modern audiences. The producing bench is deep: Ackles, Terris, Charles Gogolak and Matt Leipzig for Modern Literary Arts, Howard Braunstein, Michael Jaffe, John Requa, Glenn Ficarra, and John Weber executive produce, with Sandford listed as co-producer. MGM Television and Take 5 Productions are behind the season.

The order further cements Ackles’ standing inside Amazon MGM Studios. He is already starring in and producing the The Boys prequel Vought Rising, returning as Soldier Boy for a 2027 premiere, and previously headlined the Prime Video thriller Countdown while continuing his Supernatural legacy with fans worldwide. He is also set to return as Russell Shaw in season four of CBS’s Tracker. For MGM+, Rules of Prey extends a relationship that earlier included Terris’ Perpetual Grace, LTD for predecessor Epix—another Wright-championed crime drama that prized character texture over pure procedural churn.

Book adaptations of long-running thriller catalogues have become a streaming arms race, and Sandford’s Minneapolis-centered universe offers both a self-contained first-case entry point and years of sequel runway if audiences lock in. Eight episodes is a substantial canvas for a single novel, which leaves room for character embroidery around Davenport’s exile, the city’s institutional politics, and the killer’s coded taunts. Sackheim’s early involvement suggests the show will lean into atmosphere and set-piece tension rather than flat police-box dialogue—useful when the antagonist’s “rules” are as important as the detective’s badge.

Industry watchers will also note how cleanly the order fits Amazon’s multi-platform web. MGM+ gets a prestige crime flagship; Prime Video keeps Ackles busy as Soldier Boy; broadcast CBS retains him on Tracker. That spread reduces the risk that any single release window owns his entire calendar, while still letting marketing teams cross-pollinate fans who discovered him through supernatural lore, antihero satire, or network procedural grit. Sandford’s paperback audience, meanwhile, arrives pre-sold on Davenport’s intellect and moral stubbornness—assets that travel well when a streamer needs more than vibes to justify an eight-episode order.

No premiere date has been announced beyond the production start in Toronto this month. What is clear from Deadline and Variety is the industrial bet: a recognizable star with proven dual-duty producing chops, a showrunner coming off awards heat, a director with prestige-thriller credits, and a book brand that already owns decades of paperback loyalty. For viewers who followed Ackles from Winchester lore to Soldier Boy swagger, Rules of Prey points him toward a colder, more methodical register—one where Minneapolis winter, moral codes, and a killer’s game board matter as much as the badge he no longer formally wears.
