Hello everyone
Every year (well, not so much in 2020) I gather up all the open air film screening information that I can find for events in London and stick them in a big Google Sheets spreadsheet.
2021's is here bit.ly/OpenAirCinemaLondon2021
At the time of writing the numbering starts at 88 because there have already been 87 screenings since 12 April when I first gathered them together (all previous ones are in the 'Past' tab).
Quite a few providers haven't published their listings yet (eg Somerset House which has its season in August), but I check them all periodically and add in any new films I come across.
Many of the providers also screen films in other cities in the UK, though I only add the London ones to the spreadsheet (cos I live in London) but it's fairly straightforward to track back to homepages to get to a different city. London certainly is well-served by the open air cinema genre! Generally we have several events each night in the height of summer and many are free, put on by sponsors. Some are rather quirky (they tend not to be free).
This weekend just gone I watched Stand By Me (free) outside at the Garrison Church in Woolwich, which is tolerably near me in Blackheath. It was lovely and my first event outside the home in over a year.
