Nicola Coughlan has announced one of her biggest projects to date

Coughlan will star in the upcoming series titled I Am Helen.

She follows in the footsteps of Kate Winslet, Lesley Manville, and Letitia Wright.

In 2023, Kate Winslet led the double BAFTA-winning I Am Ruth to remarkable critical acclaim.

Coughlan will star opposite Gangs of London actor Joe Cole in I Am Helen.

The latest instalment of the I Am... series is created, written, produced, and directed by BAFTA-winning filmmaker Dominic Savage.

Speaking about the project, Coughlan said it is an honour to work with director Dominic Savage.

The Derry Girls actress said: “It’s an absolute honour to be part of telling the next I Am… story alongside Dominic Savage — a singular talent and a storyteller deeply committed to exploring the breadth of the female experience.

She also said she feels "fortunate" to have worked on this project.

"To follow in the footsteps of the brilliant women who’ve collaborated with him on this series feels truly surreal, and I feel incredibly fortunate to be embarking on this journey."

I Am Helen will air on Channel 4, but the release date has not been confirmed.

Nicola Coughlan is best known for her roles in Derry Girls, Bridgerton, and Big Mouth.
