It's a pity Brooker didn't have some residual IP control so it could have been republished elsewhere. I honestly think it was a little masterpiece that deserved to be saved.

This is really exciting, but I'm having an immense amount of trouble finding the single 1080p-quality release that is listed as known to work.

Edit: For that matter, I actually can't seem to find the 720p releases either.

Not sure if any of these work but worth a try:

I am not an expert but as long as the video is playable by the browser (x264 - Chrome apparently supports the most formats) and the same duration (05:12:14) it should work.

This is from 7 years ago but you can see if there's any helpful discussion attempting to use the initial release: https://www.reddit.com/r/Bandersnatch/comments/adnn2h/github...
