The other is Countdown, a new thriller series coming to Prime Video in which he plays an LAPD officer recruited to a secret task force as a sinister plot starts to emerge.

The show comes from creator Derek Haas, and when it was first announced Ackles said in a statement: "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.

"I simply cannot wait to partner with Derek and the rest of our Countdown family to bring this story to life."

But what is the series about, who else is set to star and when will it be released? Read on for everything you need to know about Countdown on Prime Video.

When will Countdown be released on Prime Video?

We don't yet know when Countdown will be released on Prime Video, but we would certainly expect it to arrive at some point in 2025.

In November 2024, Ackles posted some behind-the-scenes photos from the set on Instagram (above), saying that the team are "well on our way" when it comes to the show's production.

We will update this page once we get a better sense of when Countdown will stream on Prime Video.

What will Countdown be about?

Countdown will tell the story of Ackles's character, LAPD officer Mark Meachum, who is recruited to a secret task force featuring agents from a host of law enforcement agencies, after a suspicious murder is committed in broad daylight.

He and the team soon come to realise that a more sinister plot is at play, and they must put aside their competing agendas in order to save a city of millions.

The series comes from Derek Haas, who is best known for his work on the One Chicago franchise - he co-created both Chicago Fire and Chicago PD, and helped to develop Chicago Med and Chicago Justice. He is also one of the creators on FBI: International.
