The new six-part series will see Keeley Hawes (The Missing, Line Of Duty) reprise her role as matriarch Louisa Durrell.
Josh O’Connor (God’s Own Country), Callum Woodhouse (Cold Feet), Daisy Waterstone (And Then There Were None) and Milo Parker (Mr Holmes) will also reprise their roles as Louisa’s spirited and slightly wayward children, Larry, Leslie, Margo and Gerry; and Greek actor Alexis Georgoulis (My Life In Ruins) will return as chauffeur and love interest, Spiros.
The series is produced by BBC-owned Sid Gentle Films Ltd and written by BAFTA award nominee Simon Nye (Men Behaving Badly, Reggie Perrin).
The firm’s founder, Sally Woodward Gentle, said: “We couldn’t be more delighted to be making more of The Durrells with our exceptional team and on the magical island of Corfu – it is a dream come true.”
ITV’s Senior Drama Commissioner, Victoria Fea, added: “The Durrells has proven immensely popular with viewers and critics alike, so we’re thrilled to have commissioned another series.
“Simon Nye’s writing is witty, big-hearted and hugely engaging, so we’re looking forward to seeing what the fourth series has in store.”
