Yes, you read that right, and you can see it here.

Anyone who doesn't feel like clicking the link, it's just a brief clip showing shoppers in Diagon Alley before the camera cranes down to see the window of Flourish and Blotts. Inside is a book cover depicting Gilderoy Lockhart in a straightjacket.

I grew up learning to read on these books. I've won competitions, theorised, written novels-length fanfictions for the series. And I had no idea this existed until now.

Anyway, that's my mind blown enough for today. I'm going to go sit in a corner now.
