Query: Very British Dark Comedy

I happen to be a big fan of British comedies, even though I'm American. I rented "Keeping Mum" because I enjoy Rowan Atkinson's performances, and even though he's not really the central character in this movie, he does a fine job -- as do all the actors. Indeed, the casting is just about perfect.The movie manages to make light of a number of basically grim topics - most notably murder - and it's definitely not for the kiddies. But if you like wry humor, and aren't put off by swearing, partial nudity, and a lot of violence (mostly off-screen) then "Keeping Mum" will tickle your fancy.
