Now the BBC have announced that they are also heading to Spain for a two-part special with Nicola Walker's Hannah and family, as Toby Stephens joins the cast.

In the special, the Defoes are back and have gathered for a beautiful wedding in a vineyard in Catalonia's wine region. Set over a sun-drenched weekend, The Split special includes breakups, reunions and plenty of romance.
Stephens plays new character Archie Moore, while most of the original cast returns.
“In a world of brutal break ups and tantalising make ups, the Defoe family are invited to a destination wedding of their own, promising all that audiences have grown to love about The Split,” said Morgan.
The Split, which aired on Sundance TV and BBC America in the US, was one of the BBC's most popular new dramas in recent years and has been sold to almost 120 countries, with four local adaptations. The spin-off was on a mega BBC list earlier this year and is written by Ursula Rani Sarma.
The series is produced by Chernobyl maker Sister and sold by BBC Studios. The Split special was written by Morgan, directed by Giulia Gandini and produced by Jennie Fava. Executive producers are Jane Featherstone, Lucy Dyke and Morgan.
