"Countdown" Canceled after One Season

Amazon Prime Video has canceled “Countdown” after one season.

The drama, headlined by Jensen Ackles, aired earlier this year and is produced by Amazon MGM Studios. The freshman show appeared on Nielsen’s top 10 streaming originals chart.

Created by Derek Haas, “Countdown” followed an LAPD detective who is recruited to an undercover task force to track down the murderer of a Department of Homeland Security officer.

The search for the killer reveals a dark conspiracy, sparking a race against the clock to save Los Angeles.

Ackles shared his thoughts in a video on social media after the show's cancellation and to express his gratitude for the opportunity to be part of the show.

“As some of you may have seen already, Countdown did not get picked up for another season,” the Supernatural alum said in an Instagram video. “Amazon’s gonna let it go, and it’s a bummer because I had such an amazing time making that show. Had an absolute blast with the cast and the crew.”

Ackles thanked Amazon “for giving us the opportunity ” and gave a shoutout to the executives, writers and creators of the series.

“Sometimes you can set out to do your best and check all those boxes, and ultimately it’s out of your hands,” he added. “That’s the way it goes in this industry.”

Ackles noted that he was “thankful for the experience,” adding, “We’ll see you down the road on something else, I guess.”

His longtime Supernatural co-star, Jared Padalecki, commented on to the news, writing: “Their loss brother. You were amazing in it. Which is no surprise to ANYBODY. I’ll still be re-watching. And I can’t wait to see what you do next.”

Earlier that day, Prime Video opted not to move forward with "Countdown" and "Butterfly," headlined by Daniel Dae Kim, after one season for each series.

The cancellations were not a foregone conclusion, especially for "Countdown," which, more than a month after its Season 1 finale, continues to linger on Prime Video’s U.S. Top 10, currently at No. 10.

Prime Video recently made decisions on other series, too, renewing “We Were Liars” and “Overcompensating” and canceling “Motorheads.”

The streamer also renewed the crime thriller “Ballard,” a spinoff of “Bosch.”
