Check Out the New Cast Members in Big Mouth Season 6

Big Mouth is back for its sixth season of exploring the scary, horny, confusing world of tweenage sexuality with intelligence, sensitivity, and unabashed raunch. As with every new season, we've been gifted a new crop of characters — some regulars, others making one-off appearances — portrayed by an array of starry voices. This season is an especially intriguing mix of new characters, including a love interest for Missy (Ayo Edebiri), a newfound relative for Nick (Nick Kroll), and a trio of potential boy-band daddies for Lola (also Nick Kroll).

Here's our handy guide for which new characters will be voiced by which notable performers. No more racking your brain trying to place that harsh Scottish brogue or twangy Broadway belter! We've got you.

Brian Tyree Henry as Elijah

There's a new kid at Bridgeton Middle School this season: His name is Elijah, and he immediately catches the eye of Missy and her Hormone Monstress (Thandiwe Newton). Elijah's just moved from Virginia, seems pretty religious, and will be a huge part of Missy's storyline all season. He's voiced by Brian Tyree Henry, probably best known for his Emmy-nominated role as Alfred on Atlanta, but who's been an increasingly major presence in movies, playing a crime boss in Widows, a superhero in Eternals, and as of next week can be seen in the Apple TV+ movie Causeway, opposite Jennifer Lawrence, in a role that earned him a Gotham Award nomination.

Chris O'Dowd as Flanny O'Lympic

In one of a handful of crossovers from the Big Mouth spinoff Human Resources, we're introduced to love bug Flanny O'Lympic, who has been assigned to Andrew (John Mulaney) now that he's falling for his long-distance girlfriend Bernie Sanders (Kristen Schaal). He's voiced by Chris O'Dowd, beloved Irish crossover actor who broke through in the U.K. on The IT Crowd and then in America with roles in Bridesmaids, Girls, and starred in the Epix series Get Shorty.

Peter Capaldi as Seamus MacGregor

Peter Capaldi plays cantankerous and mean quite well, as evidenced by his role as Malcolm Tucker on the British TV comedy The Thick of It and the related film In the Loop. It's why it's so funny that his other best-known role has been as the 12th Doctor on Doctor Who. He'll be providing the voice of Seamus MacGregor, a mean old Scottish brawler (well, nipple-twister, really) who is Nick Birch's long-lost grandfather.

Juliet Mills as Rita St. Swithens

Rita St. Swithens appeared on the first season of Human Resources as the mother of the David Thewlis-voiced Shame Wizard. Then, she was voiced by Dame Helen Mirren. In her appearance on Big Mouth this season, where she presides over a triptych of stories about "Vagina Shame," she'll be voiced by English actress Juliet Mills. The sister of The Parent Trap actress Hayley Mills, Juliet starred opposite Jack Lemmon in the Billy Wilder-directed Avanti! in 1972, but is probably best known to contemporary audiences as the witch Tabitha from the now-canceled daytime soap Passions.

Annaleigh Ashford as The Rice Purity Test

Stage and screen actress Annaleigh Ashford provides the voice of an anthropomorphized quiz on this season of Big Mouth, proving she really can do it all. The middle schoolers start passing around the latest iteration of the decades-old Rice Purity Test, one of those questionnaires that get circulated from time to time, asking respondents to check off everything they've done from hand-holding to kissing to having sex in public and contracting an STI. The scores — and what they say about their relative levels of shelteredness or wanton depravity — send everybody into a tizzy, but not before the Test herself gets to perform a song. It's a good fit for Ashford, whose Broadway work includes the musicals Kinky Boots, Legally Blonde, and Hair. She won a Tony Award in 2015 for the play You Can't Take It With You, played Paula Jones on American Crime Story: Impeachment, and most recently starred on the canceled CBS sitcom B Positive.

Tyler the Creator as Jesus

One of the items on the Purity Test regards dancing "without leaving room for Jesus," something that intrigues Missy and terrifies Elijah. And, this being Big Mouth, it means we're getting a cameo from JC himself, voiced by rapper and Odd Future founding member Tyler the Creator. Tyler's had voice roles on animated series like Axe Cop and The Jellies!, as well as a couple appearances on the Jim Carrey Showtime series Kidding.

Cole Escola as Montel

If you watched Human Resources, you know that the first season ended with Maury the Hormone Monster (Nick Kroll) getting pregnant by Connie (Maya Rudolph), and her uneasiness with the idea of becoming a mother. That storyline gets carried to term on Big Mouth this season, and the non-binary child they birth is Montel. The kid will be voiced by non-binary comedian and cabaret performer Cole Escola, who is probably best known their roles as Matthew on Hulu's Difficult People and Chip Wreck on Search Party.

Jeff Goldblum as The Apple Brooch

You know Jeff Goldblum! He's Jeff Goldblum! He played Ian Malcolm in Jurassic Park and the stammering man who was right about everything in Independence Day and the Fly in The Fly. He's also recently appeared in everything from Thor: Ragnarok to Search Party, in addition to hosting the series The World According to Jeff Goldblum on Disney+. He'll be providing the voice of the Apple Brooch, the brand new must-have tech gadget that has everybody on Big Mouth scrambling for the status that is conferred on them by having one.

Ed Helms, Adam Levine, and Matt Rogers as Bros 4 Life

We couldn't have a new season of Big Mouth without a big story for Lola Skumpy, and this one's major. A paternity mystery arises, and as with all great fictional paternity mysteries, it's going to get solved by an homage to Mamma Mia!. Three members of the "famous post-9/11 boy band" Bros 4 Life appear on Lola's doorstep, each one being her possible dad. The Bros are voiced by The Office star Ed Helms, The Voice judge (and also Maroon 5 frontman) Adam Levine, and I Love That for You and Fire Island star Matt Rogers, and obviously there will be boy-band production numbers aplenty.
