It was last autumn when I met the ex-Location Manager of Downton Abbey. I say ex because filming had ended after 6 years and the last series was aired over the winter. He came to One Great George Street looking for a location to shoot something else.
I was a fan of Downton from the beginning as I was of Upstairs Downstairs which I watched as a child in the 1970s. There was a new pilot series of Upstairs Downstairs shown in 2012 which excited me greatly but I think it got swamped by the huge success of the much grander Downton Abbey.
