The Canadian-Irish comedian will play a single mother in The Duchess, an upcoming six-part show, Variety reported.
The Duchess will be executive-produced in part by Clerkenwell Films, the British company that previously worked on the acclaimed dark comedy-drama The End of the F***ing World.
Ryan, who has an eight-year-old daughter with a former boyfriend, will star as a “fashionably disruptive single mum” who adores her daughter Olive – and is considering having another child with Olive’s father despite their conflictual relationship.
The performer has a well-established relationship with Netflix.
She taped a stand-up special titled Katherine Ryan: In trouble for the streamer last year and is scheduled to record a new one in the US.
Ryan, a regular guest on panel shows, will also be a permanent team captain in Netflix’s upcoming unscripted comedy show The Fix, which will be hosted by Jimmy Carr.
The Fix will see guest comedians and experts attempting to solve some of the biggest issues the world is currently facing, Varietypreviously wrote.
Ryan will also act as an executive producer on The Duchess. Each episode will run for a half hour.
She’s set to tape her upcoming Netflix special on 11 December at the Belasco Theatre in Los Angeles, as a continuation to her successful UK Glitter Room Tour.
