The phrase "Mostly British" is far vaguer than it might seem at first; very few citizens of the countries that form the United Kingdom of Great Britain and Northern Ireland, which is part of but not the entirety of British Isles, cotton to being called "British." (It's a whole thing.) For that matter, this year's festival includes films from not only the United Kingdom and Ireland, which most Americans would readily quantify as being British (much to Ireland's chagrin), but also Australia and South Africa, which is seriously kicking it old-school, colonially speaking. And the films in this year's Mostly British Film Festival are also a combination of the old and new schools, kicking off with Yann Demange's award-winning '71 from last year, about a raw British recruit left to fend for himself on the streets of Belfast during the Troubles. Going considerably further back is Lindsay Anderson's 1968 if..., starring a pre-Clockwork Malcolm McDowell as a young man who foments rebellion at a posh boarding school. Even better, international treasure McDowell himself will appear in person for a Q&A before a screening of his turn as famed Englishman H. G. Wells in 1979's Time After Time, directed by American Nicholas Meyer and shot largely in San Francisco. It doesn't get more mostly-British than that.
