Mila Janssen

Mila Janssen turns up in the crowded hallways and hormone-addled chaos of Big Mouth's middle-school world, one more kid navigating puberty's indignities alongside Nick, Andrew, Jessi, and the rest. She's sketched with the show's usual bluntness — awkward, funny, unfiltered — a small piece of its sprawling, gross-out ensemble.

Big Mouth's trick is stuffing every corner of its cast with specific, embarrassing truths, and voicing her through Nick Kroll — an actor who already juggles half this show's roster — puts her inside that shared comic machinery. Even in a minor role, that pedigree promises a joke landing somewhere true and cringingly recognizable.
