‘Grimsburg’: Cast, Plot, and Everything We Know So Far About the Adult Animation Series

Jon Hamm seems to be going all in with his detective roles. The upcoming animated sitcom, Grimsburg, will see the Mad Men star slipping into his investigative shoes once again, voicing the role of ace detective Marvin Flute. Created by Catlan McClelland and Matthew Schlissel, the series follows Marvin, the greatest detective ever in the fictional town of Grimsburg, who has a hard time figuring out his own family. Although Hamm has played detectives and government agents in several films earlier, including 2022’s Confess, Fletch and the recently released Maggie Moore(s), his role in Grimsburg is one of the rarer ones on the small screen.


The only major American broadcast network to air animated series at primetime slots, FOX ordered Grimsburg as a straight-to-series in October 2021, with an announcement for a second season renewal in October 2022, even before the series hit the screens. Per FOX’s Michael Thorn, “Everything we’re seeing with Grimsburg – from the very first scripts and show bible to animatics and preliminary cuts – makes us believe we have a winner on our hands that beautifully complements our animation brand”, hinting at the show’s potential for being as successful as the other sitcoms currently running on the network. That being said, Grimsburg is not the only new show they’ve been putting so much faith in. Another upcoming FOX sitcom, Krapopolis, produced by Dan Harmon (Rick and Morty), has also received a renewal order ahead of its premiere. Both the sitcoms were earlier set to premiere in the 2022-23 season but were postponed and will join the network’s popular Animation Domination programming block, which currently includes The Simpsons, Family Guy, Bob’s Burgers, The Great North, and Housebroken. Though the show’s release date is still undisclosed, you can check out our handy guide below to find out about the plot, cast, characters, and everything we have so far about Grimsburg.

However, with the ongoing WGA and SAG-AFTRA strikes rocking the world of film and television, the network may make significant changes to its plans for Fall 2023.

Stay tuned for the latest updates on the release date of Grimsburg.

A FOX original series, Grimsburg will exclusively air on the network during their Sunday primetime programming slot. You can also watch the episodes later on FOX’s website.
