Speaking of lost Doctor Who episodes, I'm honestly surprised Loose Cannon Reconstructions was able to make a watchable version of The Massacre considering that there is functionally no visual record whatsoever of that story (not only is the entire story missing from the BBC's archives, it's one of the very few completely missing stories where there isn't even a single frame of surviving footage (and there are no telesnaps either, the only visual record of the story are some production stills taken during filming for promotional purposes, that's it).
