Sharing she found filming Call the Midwife, Molly said: “In my first episode, I was filming a lot with the lovely Linda Bassett.
“I was so grateful to do that in the first few days because she was just so kind and welcoming and helpful.
“In my first few days, we had a birth to do, which is quite scary when you haven’t done it before.
“But Linda’s just such a calming, warm presence, and she really helped me during that. Playing a nun, I also had a lot of scenes with Jenny and with Judy.
“So it was lovely just working with all of them and becoming one of the sisters at Nonnatus.”
The new character, Sister Catherine, will make her debut in episode four when she begins her midwifery qualification at Nonnatus House.

Hitning what to expect, the BBC said: “Sister Catherine keeps her distress from most of her housemates, though Sister Julienne is aware of the situation.
“But the closer Catherine gets to taking her First Vows, the more afraid she becomes. Is she doing the right thing?
“Can a life lived in the service of God and strangers ever justify the pain she has caused to those who have loved her all her life?”
