Sex Education Season 4 Introduces Loads Of New Cast Members. Here's Where You've Seen Them Before

The final series of the hit Netflix teen drama is streaming now.

The fourth and final season of Sex Education is finally here, where cast members Asa Butterfield, Emma Mackey, Gillian Anderson, Ncuti Gatwa, Aimee-Lou Wood and Connor Swindells have all returned for one last outing in the hit teen drama.

But the final season also welcomes a host of new characters to Moordale and beyond, including Dan Levy of Schitt’s Creek, Lisa McGrillis from Last Night In Soho and Doctor Who actor Thaddea Graham.

The new season is set to follow Otis and Eric’s start at Cavendish Sixth Form College, which takes a “student-led approach” where kids are “popular for being… kind”, according to Netflix, after the closure of Moordale Secondary.

Stars that will not be returning, however, include Simone Ashley, who played Olivia, Patricia Allison and Tanya Reynolds who starred as couple Ola and Lily, and Rakhee Thakrar, who played teacher Emily Sands.

Season four sees Maeve (Emma Mackey) hop across the pond to study at an Ivy League college in the US. It’s there, at the prestigious Wallace University, that she’s tutored by cult author Laurie Nunn, played by Schitt’s Creek actor Dan Levy.

Dan shared the “VERY serious news” on Twitter/X last month, where he posted a picture of his character alongside Meave.

The British actor plays Jean Mulburn’s (Gillian Anderson) sister Joanna in season four of Sex Education. Her previous acting credits include Last Night In Soho, and TV shows Best Interests, Maternal, Somewhere Boy and Avoidance.

It’s likely her storyline will weave into Jean’s journey of being a mum again, after a paternity test revealed her boyfriend Jakob wasn’t actually the father of her newborn daughter.

Queen & Slim and Anne Boleyn actor Jodie Turner-Smith was personally invited to join the show by Ncuti Gatwa.

“First of all all my scenes were with Ncuti Gatwa who – I DIE for him – and he’s my favourite character on the show,” she said on the red carpet at the BAFTA Film Awards earlier this year (published in Variety).

“So when he called me and asked me to do it I was like, I don’t care how much they’re paying I’m doing.”

We won’t spoil who Jodie’s character is, but she has a connection to Ncuti’s much-loved character, Eric.

Eshaan makes his on-screen TV debut in Sex Eduction as Principle Lakhani, having previously served as a voice actor on Spitting Image and featured in the 2021 short Sometime Else.
