LONDON — U.K. commercial broadcaster ITV has commissioned a second season of its hit family drama “The Durrells” after airing just two episodes of the first run. The series, produced by Sid Gentle Films, is ITV’s best-rating new drama of the year and its highest-rating new show since September 2014.

The first episode launched on ITV with 6.4 million and a 29% share — the channel’s best new drama since “Cilla” in September 2014. The first episode has since consolidated to 8.2 million and a 33% share, making it the most watched ITV drama of this year.

“The Durrells,” Simon Nye’s adaptation of Gerald Durrell’s trilogy of memoirs, tell the story of Louisa Durrell who makes a radical change and uproots her four unruly children — Larry, Leslie, Margo and Gerry — from Bournemouth, England to start a new life in Corfu in the 1930s.

Keeley Hawes will return as matriarch Louisa alongside her fictional brood played by Josh O’Connor (Larry), Callum Woodhouse (Leslie), Daisy Waterstone (Margo) and Milo Parker (Gerry).

Sally Woodward-Gentle, CEO at Sid Gentle Films, said: “The combination of Gerald Durrell’s warm, witty stories and Simon Nye’s brilliance at adapting them meant we always knew that we had created something special.”

Filming on the second season will take place later this year in Corfu.
