Speakers' Corner - the short film above - was shot by James D Lyndon in March, 2012 for Worn & Torn Films. It is shot beautifully, with James stating that:
The film aims to capture the atmosphere of Speakers' Corner in a kind of montage of sight and sound. Even the music comes from a street busker who I saw as I was just about to leave.
I think the film does a good job enticing you to visit the Hyde Park institution. However, don't be surprised if your actual experience is bit less relaxing than what the video shows. From my experience Speakers' Corner is packed with people each Sunday. Still definitely worth a visit.
