Kate Winslet and Mia Threapleton are set to star in the first feature length episode of Channel 4’s I Am.

The special episode of the award-winning female-led anthology series from BAFTA-winning writer-director Dominic Savage is due to begin filming this month.

Winslet will play the lead role in I Am Ruth opposite her daughter Mia Threapleton.

Speaking about the role, she said: “I have always admired Dominic’s work and, in particular, his commitment to telling real stories. British television is at an all time high, and I feel excited and honoured to be part of this community, especially right now.”

Savage added: It is a complete honour for me to be working and collaborating with Kate Winslet on this first film of the new series of I Am for Channel 4.

“Kate is such a legend, such an incredible and sublime acting talent, and I can’t wait to start shooting this unique and important story that we have created together.”
