Season 4 of Netflix hit Sex Education is on its way... Asa Butterfield will return as Otis Milburn, and bonafide legend Gillian Anderson will be back as his sex therapist mother, Dr Jean Milburn. Ncuti Gatwa, who was confirmed as the next Doctor in Doctor Who, will also be back as Otis's larger-than-life best mate Eric Effiong. And Emma Mackey, who is Otis's will they/won't they love interest Maeve Wiley, is back in business (albeit starting the series in the US) shortly after finishing filming alongside Margot Robbie in Greta Gerwig's Barbie movie. We have a brand new setting in the form of Cavendish Sixth Form College where the likes of Otis and Eric will have to get used to new surroundings, while Maeve deals with her education in the US under the tutelage of a cult author, played by Schitt's Creek star Dan Levy. Tanya Reynolds, Rakhee Thakrar, Simone Ashley and Patricia Allison are amongst the cast members not returning for the fourth season.
