"The Polly and Tommy scenes were some of my favourite scenes in the show. It's desperately sad. We're all still trying to come to terms with it."
Helen, who played Polly Shelby in the hit show, tragically passed away in April 2021 following a battle with cancer. Paying tribute to her at the time, Cillian said: "I am broken-hearted to lose such a dear friend. Helen was a beautiful, caring, funny, compassionate human being. She was also a gifted actor - fearless and magnificent. She elevated and made humane every scene, every character she played.
