The first looks of Sex Education series' fourth and final season were released by the makers on social media recently. The fourth season is set to premiere on September 21.

The new looks show Otis and Eric sharing a laugh, Maeve studying abroad, Jean and Otis with the former's newborn. The upcoming season will follow the students of Moordale moving to Cavendish Sixth Form College only to realise how the college is very different from their previous one and in fact, more forward thinking.

The fourth season has already been buzzing as some of the central cast announced their departure from the series in further seasons, including  Emma Mackey, who plays Maeve and Ncuti Gatwa, who adorned the character Eric. Ahead of the fourth season filming, a few have already bid their adieu, including Simone Ashley, Tanya Reynolds, Patricia Allison, and Rakhee Thakrar.

Sex Education also has major casting shifts as a new addition to the cast, including Jodie Turner-Smith, Dan Levy, Thaddea Graham, Marie Reuther, Alexandra James, Anthony Lexa, Felix Mufti, and Imani Yahshua.

The returning cast of the series includes Asa Butterfield, Gillian Anderson Connor Swindells, Alistair Petrie, Kedar Williams-Stirling, George Robinson, Chinenye Ezeudu, Dua Saleh, Mimi Keene, and Samantha Spiro.
