Kwouk had a long and varied career, mostly playing East Asian supporting roles. These ranged from playing a brutal Japanese camp commandant in the series Tenko, to long running British sitcom Last of the Summer Wine, about a group of elderly Yorkshiremen who get into frequent trouble, to a number of British TV commercials.
However, Kwouk was perhaps best known for his recurring role as Cato Feng in the successful Pink Panther film series by Blake Edwards and which featured comedian Peter Sellers, who also starred in Casino Royale. In 1990 he provided the voice of Ando in a radio play of You Only Live Twice. Kwouk died on 24 May 2016, aged 85.
