Just as a matter of interest, Swan Yard appeared in a British film of 1952 called 'The Long Memory', starring John Mills, John McCallum, Elizabeth Sellars, Eva Bergh, John Slater, and Geoffrey Keen.
In one night scene John Mills' character is watching a house in Queen's Street, waiting for John Slater to surface. However, unknown to Mills, the police (in the company of a journalist) are watching the street too, waiting for John Mills who's bent on revenge, having gone down for a crime he did not commit.
Now the house in which Slater is esconced, was on the west side of Queen's Street, and when he does make a run for it, he dashes into Swan Yard to make good his escape. True, it is a fleeting glimpse of the Yard, but if you're interested in the area, it's marginally better than nothing! At the bottom of Queen's Street can be seen the riverside church of St. Andrew, and the scene generally gives an interesting panorama of the old quarter of Gravesend before it was redeveloped, and eventually bled to death in the 1960s.
And just for good measure, it's a damned good film too!
