Jenny Agutter has been pictured on set in character as Sister Julienne.

Filming on the eighth series of Call The Midwife is under way.

A picture posted on the show’s official Twitter page shows cast member Jenny Agutter back in the habit, with a clapperboard reading “Slate 1, Take 1” in her hands.

“It’s happening!!! Series 8 of #callthemidwife has just started filming!!” the message says.

The BBC drama’s seventh run ended in March with a tear-jerking instalment that saw the midwives of Nonnatus House still reeling from the death of Barbara.

As it wrapped, many viewers posted messages on social media saying they were wondering how to cope without their fix every week.
