"It is with great sadness we can confirm that Paul Ritter passed away last night. He died peacefully at home with his wife Polly and sons Frank and Noah by his side. He was 54 and had been suffering from a brain tumor," the agent said.
"Paul was an exceptionally talented talented actor playing an enormous variety of roles on stage and screen with extraordinary skill. He was fiercely intelligent, kind and very funny. We will miss him greatly," they continued.
Ritter portrayed Anatoly Dyatlov in Chernobyl and family patriarch Martin in Friday Night Dinner. He is set to appear in a 10th anniversary retrospective on Friday Night Dinner that will air on Channel 4 later this year and war drama Operation Mincemeat alongside Colin Firth.
