(moving music) - In this series, Ross has become an MP.
So a lot of the show has moved to London.
It's a much more sophisticated, bigger world.
London was a huge, thriving metropolis.
It was actually much smaller, of course, than what we think of it now.
There are bits of London that haven't changed.
Fortunately there are heritage areas.
We've looked for buildings that have had columns and pediments, pushing the scale of London.
- [Director] And action!
- We've used Greenwich as the area around the House of Commons.
In Bristol we've gone to the old part of the city near the old St.
Nicholas Market where there are closes, narrow alleyways which were built in the 18th century and we've used that for Ross' lodgings.
Those kind of areas were very crowded.
A lot of poor living in the streets.
We've used straw and earth and old bits of food lying around just to rub it up and if you look at the great, kind of Hogarth engravings from the mid-18th century it was teeming with people but there was also a fashionable side, a separate world from the poor.
- Surely, the starving poor should be thanking you.
- [Jeff] The Warleggan house, very grand, very fashionable.
Probably in Mayfair.
- Quite.
- And then they meet across the Houses of Parliament and they also go to the social areas of London, to the pleasure gardens, to the theaters, the gaming houses, London clubs which were all being built and developed at that time in which became terribly important for society.
Cornwall, the sea, Nampara, we spent a lot of time just keeping that world real so that they can use it as a base to go out, explore other things.
But they always get drawn back.
