Born into a leading titled family, Sister Monica Joan was one of the first women in Britain to qualify as a midwife. In the closing years of the 19th century, this was seen as a radical act. Her additional decision to become a nun scandalised her relatives, who never came to terms with her life choices. She dedicated her entire adult life to providing midwifery services to the poor of the East End.
Now in her 90s, Sister Monica Joan has retired from practice, but lives full-time at Nonnatus House, cared for by her fellow sisters. She has an eccentric, mercurial personality, and is obsessed with cake, astrology, the Space Race, and knitting, in no particular order.
It is never entirely clear how much of Sister Monica Joan's eccentricity is due to the frailty of age or sheer wilful naughtiness. She is often questioning of her usefulness and delights in the occasional opportunity to put her rusty skills to use under the close supervision of her colleagues. In Season 12 when a gastroenteritis outbreak sweeps through the maternity home, she steps in as a nurse and helpful hand, using her decades-long worth of knowledge to help the mothers and daughters who have fallen ill.
Toward the end of Season 12, the midwives and nurses receive a scare when Sister Monica Joan falls gravely sick after contracting hepatitis, however, she fortunately makes a recovery – and even makes an appearance at Trixie and Matthew’s wedding to recite a reading.
Season 13 sees Sister Monica Joan fall into a deep depression as she is further convinced that this upcoming Christmas will be her last one. Eager to try and raise her spirits, Sister Julienne calls on Dr. Turner to assess Sister Monica Joan, who further concludes that she is in fact depressed. Fortunately, an idea from Colette, Nancy’s daughter, offers a spark of inspiration. Earlier, Sister Monica Joan confided in Colette about one one of her cherished Christmas memories as a child: a Christmas Nativity tableau.
The nurses and midwives of Nonnatus House, as well as the community at large, come together to give Sister Monica Joan a memorable Christmas nativity tableau to remind her once again of the joys of life and friendship.
Tell us about the scripts.
They’re all authentic, because they get input from all sorts of midwives and medical people. Heidi is brilliant, she’s on the button all the time about what was happening then, they’re all completely realistic. There’s always an underlying theme that makes people think about things in a fresh way – it almost makes people think about things they hadn’t given serious thought to before.
In what way has your character grown and developed since you started?
With Sister Monica Joan, it’s difficult because she’s always danced to her own tune. She is very well educated, highly intelligent, very well read but she’s very fragile emotionally.
If you had to deliver a baby for real do you think you could do it?
As I’ve given birth myself, I would obviously have some idea to a certain extent, but would always feel a necessity to call a midwife!
Do you enjoy playing Sister Monica Joan?
I do enjoy playing Sister Monica Joan because she’s multi-coloured and unpredictable. It’s not an easy ride because she’s complex and that’s why I love her and like doing it. She sometimes loses the plot and other times she’s incredibly sensible, helpful and guiding. She constantly shifts and changes and that needs to be thought about a great deal because she goes from one extreme to the other. You have to find a way through it which is a challenge. She’s tricky but I love that I can really do anything with her, and that she loves cake! She’s totally obsessed with cake; it’s like a drug for her.
She’s very broad minded and not judgemental unlike the young ones. She often sits there with them and says there’s nothing wrong with being different.
She likes to muddy the waters but not in a cruel way, only in a mischievous one.
What is the secret to the success of the show?
I tell the young people on set to make the most of the success because it doesn’t happen to most people in this business. To get a show that is so humungously successful and adored is rare. The success of the show is down to the scripts but the casting has also been fantastic. The period detail is wonderful as well. It was only 50 years ago but you look at it and think its 500 years ago. I can’t believe that outside lavatories for blocks of tenements is in the recent past. Also, there’s no swearing and no sex although of course we do see the results of it. And no matter how many times you see a baby being born, it’s always a miracle. That never changes.
What is it like to wear the habit?
It’s not comfortable and you can’t hear because there are 6 layers of stuff covering your ears! No hair or make-up in the outfit is not a reassuring thing to live with!
Do you enjoy the music from the show?
The hymns and carols are particularly beautiful. They give such an atmosphere of the period and I love them – it’s my era so I recognise them all. Music is integral to the show and everything works well together.
What are your favorite scenes to film?
I like scenes when Sister Monica Joan is being a bit naughty; when she’s nicking things and being mischievous! What is the relationship like between Sister Monica Joan and the other nuns and midwives? They’re all very protective of her but she wants to pull her weight. She gets fed up with Sister Julienne not treating her as someone who is an attribute. Sister Monica Joan wants to be doing things and Sister Julienne is always trying to protect her and stop her from doing them.
How is it to play her failing health scenes?
I hope I strike the right note playing her. The reason I’ve got for why she behaves that way is that when she’s not feeling well, when she’s stressed and very tired her mind starts playing her up.
How much pressure do you feel to keep true to the character she is based on?
You have to be very careful about keeping it truthful, fresh and alive all the time. You have to play each scene like you’ve never played anything like it before.
