Celebrity guest stars for new Call the Midwife series revealed as filming begins

A Call the Midwife prequel, Sisters In Arms, set during 1939 and the Blitz, begins filming as a three‑part Christmas special for the BBC, focusing on the early days of Nonnatus House in east London. The project will explore the origins of the convent run by nurses, midwives, and Anglican nuns as the story returns to younger versions of beloved characters. Guest stars include Julie Hesmondhalgh as Sister Alice and Bally Gill as Dr Kit Malhotra, with Jenny Agutter narrating as the older Sister Julienne. Heidi Thomas, the show's creator and writer, emphasizes wartime resilience, motherhood, and professional duty, promising a blend of medical drama and personal histories as new actors reimagine familiar figures.
