When is the Big Mouth Season 8 release date?
All ten episodes of Big Mouth Season 8 are slated to start streaming on May 23, 2025. The show centers around a group of seventh graders as they deal with the pleasantries of growing up, including hormones, self-discovery, and sex-ed classes.
The adult animated comedy is created and executive produced by Nick Kroll, Andre Goldberg, Mark Levin, and Jennifer Flackett. The voice cast is led by series regulars Nick Kroll, John Mulaney, Jessi Klein, Jason Mantzoukas, Ayo Edebiri, Maya Rudolph, Fred Armisen, Andrew Rannells, and Jordan Peele. Since making its debut in 2017, the series has maintained an average Tomatometer rating of 94% on Rotten Tomatoes.
“In the final 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,” reads the official synopsis.
“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.”
