BBC TV - Storyville: From the Sea to the Land Beyond: Britain's Coast on Film
BBC TV said:Made from over 100 years of BFI archive footage, From the Sea to the Land Beyond offers a poetic meditation on Britain's unique coastline and the role it plays in our lives. With a soundtrack specially created by Brighton-based band British Sea Power, award-winning director Penny Woolcock's film offers moving testimony to our relationship to the coast - during wartime, on our holidays and as a hive of activity during the industrial age.
I shall post any new BBC documentaries as and when they appear.
