James Herriot's All Creatures Great and Small (TV series is far better than the film, imo) gives a good impression of the Yorkshire Dales even if from a rather different time period.
I also like Crush, which was filmed in Chipping Campden (my favorite English village) and other locations in the Cotswolds. Plus Waterland, which gives a rather evocative feeling about the Fens of East Anglia.
