The sitcom set in a book shop was probably 'Black Books'.

You may be pleased to know that the surreal exploits of Bernard and Manny are to continue into a third series.
I'm surprised.....but in a good way, that my Yank cousins are watching shows like 'Black Books'. Although, if you guys get the VERY British humour (humor) of shows like Monty Python....then I suppose anything is possible.
If you haven't already seen it, try to watch the BBC comedy, 'Blackadder'. Especially the second series (Season), which was probably the best of the four. Rowan Atkinson is the star....long before he became Mr Bean - Forgive us for unleashing Mr Bean on your nation. Not exactly Rowan Atkinson's best character....IMHO
The above named films are all great. 'The Third Man' is a cinematic masterpiece, and I'm a proud owner of the DVD. It's one of the best British films ever made.
Although, it's hard to know these days, what exactly a 'British' movie is. Does it depend on where the money comes from? For sake of arguement, I'll stick to what 'appears' to be British.
Although most of the Pink Panther movies haven't aged well, there was one gem that is always worth watching. It's an early one, entitled 'A Shot In The Dark'. Sellars was on top form.
Although in reality he was apparently a 'troubled' individual, and not always the nicest of people to be around, some of his work touches on genius -'Doctor Strangelove' being one shining example. Does that count at least as a part-British movie. The director, Stanley Kubrick, made England his home...Sellars was a Brit.....Ok, I'm pushing my luck here!
If you're a John Cleese / Monty Python fan, how about 'A Fish Called Wanda'. It also has Michael Palin...who I seem to remember has a stutter....which has unfortunate repercussions for a small dog, standing below a falling object.
