She became a household name playing Mrs Doyle in Father Ted, and it looks as if actress Pauline McLynn is back in the habit.
The 50-year-old comedienne is returning to her religious roots as she plays a nun in upcoming film Noble, a biopic tracing the life of charity campaigner Christina Noble.
Pauline looks like butter wouldn't melt as she smiles sweetly outside a convent while filming.
But don't be fooled, the Sligo native is playing the part of a stern and imposing Mother Superior.
"Deirdre O'Kane will play philanthropist Christina Noble and I'll be a nasty nun," she laughed.
Pauline and Deirdre have previously worked together on Fiona Looney's comedy play Greener.
Dundalk native O'Kane will share the lead role with actress Sarah Greene.
Greene (28) has previously starred in the Abbey Theatre's critically acclaimed production Alice In Funderland.
She played a prostitute in John Martin McDonagh's The Guard and has appeared in RTE's Bachelor's Walk and Raw.
The petite Corkonian has been dating The Hobbit star Aidan Turner for several years.
Amy Huberman's elder brother Mark – who had a role in the critically acclaimed Band of Brothers – will also star in the biopic.
Mark will play the part of English businessman David Somers, while Game of Thrones star Liam Cunningham is cast as Christina's father. Former Love/ Hate star Ruth Negga will also feature in the film as Christina's best friend, Joan.
The movie is due for release next year and was penned by O'Kane's screenwriter husband, Stephen Bradley.
It's easy to see why Christina's life is such a rich subject for a feature film.
Born in the slums of Dublin in 1944, Noble's mother married a bare-knuckled boxer, who poured their money down his throat.
After her mother died, Christina and her three siblings were sent off to three different orphanages.
Over the course of her life, she has suffered domestic abuse, had a nervous breakdown, received electroshock therapy and founded the Christina Noble Foundation, which has helped more than 700,000 children.
