In Friday Night Dinner, Ritter played the quietly-suffering, often shirtless, hard-of-hearing husband and dad Martin Goodman.

His widely-acclaimed role as Anatoly Dyatlov, the deputy chief engineer at the nuclear power plant in Chernobyl, led to the five-part miniseries becoming the best-rated show ever on global movie and TV website IMDb – and hailed as “the greatest drama of all time”.

In Harry Potter And The Half-Blood Prince, he played wizard Eldred Worple.

Other notable roles were as Guy Haines in James Bond film Quantum Of Solace, in period drama Belgravia, as Billy Cartwright in Vera and Sir John Seymour in Wolf Hall.

Ritter is due to appear in the Friday Night Dinner 10th anniversary episode, which will air on Channel 4 later this year.
