Post-WW2, BIG screen Brit-com biting satires.
From the post-WW2 Ealing black Comedies directed by visionaries like Charles Crichton and Michael Balcon, through the 1950s & '60s Boulting Brothers string of brilliance, to cutting edge Ken Loache, Lindsay Anderson and too few more - with no current peers.
Entertainingly say everything about high and low corruption in postwar Britain - then and now!
