Starring Anthony Newley, its six episodes appeared on ITV in late 1960. The opening part of episode 2 is set on an abandoned airfield, possibly in Kent, as all of episode 3 looks to have been filmed there. Any suggestions as to which airfield it was?
Yes, it was in use in 1960, but thanks. Other than the building on the horizon in the first photo, and the two in the second, the only other structure I could see onscreen was what looked like a Nissen hut. I think it's best if I withdraw the suggestion that this might be in Kent, as it looks like it was filmed at a different time of year to the next episode. The photo below shows Newley standing in the same area as in the second photo, but this view is looking across the runway to the other side. As this series was released on Blu-ray last year with a large booklet "which provides every piece of Gurney Slade trivia you could ever need," the answer will hopefully be in there.
Can't help with the location, but as a suggestion, there's the Britmovie website whish has some very knowledgeable people as members. Might be worth joining to ask there. Forums - Forums (britmovie.co.uk)
