Final Big Mouth Season to Debut on Netflix May 23

Netflix has announced that the eighth and final season of Big Mouth will premiere globally on the streaming service on May 23, 2025.

In the 10-episode season, our beloved Bridgeton teens tackle new challenges as high schoolers, such as driving, drugs, sexual inexperience, enthusiastic consent, porn, and the teenage mind, cancel culture, their changing bodies, and (in the end) fear of the looming future.

Through it all, friendship is the cornerstone for surviving this time of life – whether one’s puberty is just beginning, like for Nick, who gets his first growth spurt, or near its conclusion, like for a maturing (and prematurely balding) Andrew.

At the height of the season, when many of our characters are in crisis, Compassion (personified as a new creature voiced by Holly Hunter) emerges as a crucial way forward. Ultimately, though, this season is about the importance of sticking by and supporting your friends, especially when life gets overwhelming and messy.

In the end, our kids step into the harrowing unknown of the future, made less afraid of what’s to come because they have each other.

The series regulars include Nick Kroll, John Mulaney, Jessi Klein, Jason Mantzoukas, Ayo Edebiri, Maya Rudolph, Fred Armisen, Andrew Rannells, and Jordan Peele. The show’s executive producers include Nick Kroll, Andrew Goldberg, Jennifer Flackett, and Mark Levin.
