Here is the biography of Nigel Hawthorne at the Internet Movie Database.

IMDb lists 66 credits for him: 28 TV and 38 films, starting with an uncredited appearance as a "Boer sentry" in "Young Winston" in 1972. I will remember him mainly for "Yes, Minister" and "Yes, Prime Minister," which were shown on public TV here in the US, and for "The Madness of King George." Yes, he will be missed.
