More teenage angst and hijinks have arrived on Netflix as Season 5 of Big Mouth is streaming now.
Nick, Andrew, Jessi and Missy all return to Bridgeton Middle School for a season of romantic loves triangles, embarrassing moments and musical numbers. Love bugs and hate worms are the creatures causing the teenagers problems in Season 5, joining their hormone monsters to guide the students through puberty.
The cast list for Big Mouth seems bigger than ever in Season 5 so let's take a look at who's joining the cast, and who's returning.
New characters and voice actors in Big Mouth Season 5
Nick Kroll and the creators of Big Mouth bagged some huge guest stars for Season 5, and from the moment you hear Hugh Jackman voice a fuzzy penis in Episode 1, you know there's more to come.
The Wolverine actor plays a version of himself in the season opener while Kumail Nanjiani does the same.
Adam Scott joins the cast as the unconventional substitute teacher Mr Keating while Jermaine Clement arrives as the Hormone Monster Simon Sex.
