To mark the 50th anniversary of the release of the Sgt. Pepper’s album by The Beatles’, the BBC did a really in-depth analysis of it, presented by Howard Goodall. One childhood influence on at least two of the ‘Fab Four’ had been Lewis Carroll’s ‘Alice in Wonderland’. To emphasise that, some sequences featured clips from the BBC’s own black-and-white version of ‘Alice’ from 1966. And a brief one of those clips had me recording the repeat a few days later so I could review that bit again. Yes, it was a glasshouse. Yes, it was dilapidated (or at least run down). And yes, there was something (large) growing in it . . . it’s a vine . . . and there are grapes on it!
A quick look on IMDB told me that these sequences were filmed at Rousham House, in Oxfordshire. Again private, the gardens are open every day: the house is only open by prior arrangement.
