The latest season will also see a notable change of cast. Jenny Slate, who voiced the adorable and nerdy Nathan Fillion loving Missy would leave the show this season. In wake of the Goerge Floyd protests, Slate took to Instagram to express her feelings.

She said, “Missy is also Black, and Black characters on an aminated show should be played by Black people. I acknowledge how my original reasoning was flawed, that it existed as an example of white privilege and unjust allowances made within a system of societal white supremacy.”

Kroll along with the show’s co-creator Andrew Goldberg, Mark Levin, and Jennifer Flackett, also took to Twitter and announced that they have decided along with Slate that Missy on Big Mouth should be voiced by a Black actor.

Two months after Slate’s departure, on August 28, Variety reported that comedian and actress Ayo Edebiri was officially cast as Missy. Her first episode will be the penultimate episode of Big Mouth Season 4. Andrew Goldberg also confirmed her casting on Twitter.

Edebiri also announced her casting with a sweet throwback post.

Big Mouth Season 4: Potential Plot

Although Season 3 left a lot of cliffhangers, we see hints of what’s next in the new trailer. After the incredible third season finale, we can expect the show to go crazier in the next one.

Season 3 also saw the end of Andrew and Nick’s friendship. Up until now, their friendship was the most important aspect of the show, and how both of them helped each other grow up and help each other’s struggles.

Season 3 also introduced a new hormone monster. Mona, voiced by Thandie Newton, will be the second female hormone monster in the show and it will be interesting to see her helping Missy through her puberty as well as her interaction with Maury and Connie in Big Mouth Season 4.

However on November 13, we finally get the new trailer. Also this new trailer introduced us to a new character Seth (Seth Rogen) over whom former BFF’s Andrew and Nick are going to fight over.

Moreover like every season dealing with a theme, this season seems to focus on anxiety. A brand new character, Anxiety Mosquito has made the trailer even more fun and we can’t wait to see how the gang fights it.
