The character details for the other new additions to the cast are being kept under wraps.
Levy is currently under an overall deal with Netflix, which he signed in September 2021 following 'Schitt's Creek's' historic wins at the Emmys that same year.
In Season 4 of the popular series, following the closure of Moordale Secondary, Otis (Asa Butterfiield) and Eric (Ncuti Gatwa) now face a new frontier - their first day at Cavendish Sixth Form College.
Otis is nervous about setting up his new clinic, whilst Eric is praying they won't be losers again. But Cavendish is a culture shock for all the Moordale students - they thought they were progressive but this new college is on another level.
There's daily yoga in the communal garden, a strong sustainability vibe and a group of kids who are popular for beinga kind?! Viv (Chinenye Ezeudu) is totally thrown by the college's student-led, non-competitive approach, while Jackson (Kedar Williams-Stirling) is still struggling to get over Cal (Dua Saleh).
Aimee (Aimee-Lou Wood) tries something new by taking an Art A Level and Adam (Connor Swindells) grapples with whether mainstream education is for him. Over in the U.S., Maeve is living her dream at prestigious Wallace University, being taught by cult author Thomas Molloy.
Otis is pining after her, whilst adjusting to not being an only child at home, or the only therapist on campus.
According to Variety, other returning cast members for Season 4 of the series include Gillian Anderson, Mimi Keene, George Robinson, Alistair Petrie, and Samantha Spiro.
A number of cast members have announced they will not be back for the new season, namely Simone Ashley, who played Olivia, Tanya Reynolds as Lily, Patricia Allison as Ola, and Rakhee Thakrar, who played school teacher Emily Sands.
