The A Word, which follows a family hit by unexpected news when son Joe (Max Vento) is diagnosed with autism, is to begin filming its third series this week in the Lake District and Manchester.
The show will pick up two years on from the end of the second series, where things have significantly changed for the Hughes family. Joe is now 10 and living in two places at once, processing the major changes in his life through the filter of his autism.
Meanwhile, Alison (Morven Christie) and Paul (Lee Ingleby) are divorced and live 100 miles apart. It's only Maurice (Christopher Eccleston) who is holding things together, which isn't a good sign for the family.
As well as Hesmondhalgh, the regular cast members will also be joined by Sarah Gordy (Call The Midwife, Holby City) and David Gyasi (Interstellar).
On coming back for a third series, writer Peter Bowker said: "It is a joy to be revisiting the world of The A Word, to move the story of the Hughes family on, and to have the opportunity to expand our celebration and examination of diversity and humanity in all its myriad forms.
"The BBC has been incredibly supportive of this show and deserve our thanks and support at a time when it continues to be attacked on behalf of the ignorant by those who should know better."
The A Word airs on BBC One.
