We met a lot of lovely, enthusiastic Londoners (and visitors to the city) who were very excited about the film and happy to join in.
If you're in the video, we'd love to know who you are! And for those friendly folk who stopped us for a photo with the sign, we'd love to see it - so drop us an email.
