“Do not watch this!” Breaking the fourth wall in a video message... the wheel turns, nothing is ever new...
Sleep No More, a Doctor Who episode written by Mark Gatiss.
Here we have a Professor
Moriarty “who has been playing a long game.”
(more Sleep No More/Sherlock parallels (before s4 aired) in this episode here).
The Professor interrupts “THE END” of the story in a video message, looking directly at the camera.
They are all villains in control of the story:
“I do hope you’ve enjoyed the show. I did try to make it exciting: all those scary bits, all those death-defying scrapes, monsters, and a proper climax with a really big one at the end. Compulsive viewing. I did tell you not to watch.”
^Directly showing the idea of a story being created, (the Professor’s ALIBI). aware of it being fictional (this is the story of Sir Boast-A-Lot)… a creepy glitchy noise very like the ‘Did you miss me’ videos… a video message with a poisonous message hidden inside ( “who you really are, it doesn’t matter”/ “he planted that doubt inside her head, that little nagging sensation you’re going to have to be strong to resist”).
Compulsive viewing. Like a game show. With a time limit.
And “I did tell you not to watch” rather reminds me of one of Mark’s friends… ;)
