After a bit of a longer hiatus than expected, Sex Educationseason three is officially on its way! Netflix shared a fun video announcement with the news, which also confirmed something else: which cast members we can be sure are coming back for the new season. All of our favorite main cast members are officially on board to return, along with a trio of additions playing intriguing new characters. The official release date isn't until Sept. 17, but while we wait for new episodes, you can take a look at the gallery ahead to find out now exactly who's coming back and who's joining the cast.

Asa Butterfield as Otis Milburn

Butterfield returns as Otis, the often-awkward teenager at the center of the story.

Gillian Anderson as Dr. Jean Milburn

Following her recent run on The Crown as Margaret Thatcher, Anderson is stepping back into the shoes of Dr. Milburn, a sex therapist and loving (if sometimes embarrassing) mom to Otis.

Emma Mackey as Maeve Wiley

Mackey is back as Maeve, Otis's pal, "therapy clinic" partner, and, now, possible love interest.

Patricia Allison as Ola Nyman

Although her character breaks up with Otis in season two, Allison is back for season three, with Ola continuing to play a role in the group of friends.

Ncuti Gatwa as Eric Effiong

Gatwa's character, the openly gay Ghanaian-Nigerian teen Eric, has become a fan favorite, and it's no surprise he's back for the new season.

Tanya Reynolds as Lily Iglehart

Reynolds will be back for a third season of bringing quirky Lily to the screen.

Aimee Lou Wood as Aimee Gibbs

Wood is bringing back Aimee, the popular girl who's crossed over to hang with the decidedly less-cool main group of friends.

Kedar Williams-Stirling as Jackson Marchetti

Williams-Stirling will reprise his role as Jackson, Moordale's swimming star.

Connor Swindells as Adam Groff

Following something of a villain-to-hero arc, Swindells's Adam will return in season three.

Mikael Persbrandt as Jakob Nyman

Persbrandt is back as Jakob, Ola's dad and the handyman who falls for Jean.

Alistair Petrie as Michael Groff

Petrie is back for a third season of playing headmaster Michael Groff.

Dua Saleh as Cal

Saleh, a singer-songwriter, will join the cast in season three as Cal, a nonbinary student who clashes with the new headmistress at Moordale.

Jason Isaacs as Peter Groff

Lucius Malfoy himself, Isaacs, is slated to appear in season three, playing Peter Groff, Michael's "more successful/less modest" brother.

Jemima Kirke as Hope

The Girls star is taking over as headmistress at Moordale, playing Hope, a former student at the school who has some big ideas.

Indra Ové as Anna

Indra Ové joins the series as Anna, the foster mom of Elsie Wiley. For those of you who may not recall, season two of Sex Education ends with Maeve's mom, Erin, being taken away after Maeve notices that she's using again. As a result, Maeve's half-sister, Elsie, has to be taken into foster care.

Chinenye Ezeudu as Viv

Chinenye Ezeudu will be back in season three, continuing her role as Viv. Her character is introduced in the show's second season, and she quickly becomes good friends with Jackson (played by Kedar Williams-Stirling) after helping him with his career decisions.

Simone Ashley as Olivia

Simone Ashley, who's recently been confirmed to join Bridgerton's upcoming season, will in fact be returning to Sex Education for season three. Continuing her role as Olivia, one of Moordale High's resident mean girls, we're looking forward to seeing how her character changes.
