Jensen Ackles, the star of The Boys, will once again partner with Amazon. Derek Haas’ new Prime Video action-thriller series, Countdown, will star the Supernatural actor.

According to Variety, Amazon has ordered 13 episodes for the series. The company created Countdown as a starring vehicle for Ackles, who portrayed Soldier Boy in Prime Video’s smash series The Boys. Haas (OneChicago) conceived the series and serves as executive producer and showrunner. Amazon MGM Studios is producing the series alongside Chaos Machine, Ackles’ production business, which has a first-look arrangement with the studio.

Per Countdown‘s description, the series begins “following a suspicious murder in broad daylight, which leads to LAPD officer Mark Meachum (Ackles) being recruited to join a secret task force of undercover agents from all branches of law enforcement to investigate. But as the truth of a more sinister plot comes into focus, the team must overcome their conflicting personal agendas to unite and save a city of millions.”

Ackles is excited about the upcoming project and his partnership with Amazon. “I had an incredible experience working with the Prime Video team on The Boys and am delighted to be able to continue that relationship on Countdown,” he said. “I simply cannot wait to partner with Derek and the rest of our Countdown family to bring this story to life.”

In addition to his turn on The Boys, Ackles featured in its spinoff series, Gen V, and most recently on the hit CBS show Tracker. However, Countdown marks his first lead role on the small screen since the WB/CW series Supernatural, which ran for a historic 15 seasons, ending in 2020. Ackles also appeared in Season 3 of ABC’s Big Sky. He narrated and executive produced the Supernatural prequel series TheWinchesters.

No stranger to portraying superheroes, having played Soldier Boy and voiced Batman, Ackles has long been fan-cast as several characters in both the Marvel and DC Universe. Recently, KH Studios posted a concept trailer, imagining the actor as the Marvel Cinematic Universe’s Johnny Blaze alias Ghost Rider. The trailer blends footage of Ackles as seen in The Boys and Supernatural with clips from Agents of S.H.I.E.L.D. and Terminator 2: Judgment Day.

Amazon is yet to schedule a release date for Jensen Ackles’ Countdown. However, there are rumors he will return for Season 4 of The Boys, which premieres on Prime Video on June 13.
