Fifty Shades of Grey is mentioned as a fanfiction that was turned into a movie and became more popular than its source material.
So, you know, there's this reverse fanfiction inclusion with the author thing where you go, this has got to the I mean, Fifty Shades of Gray. Yeah. Starts off as a fanfic and then gets turned around and okay, we've gone full circle here into a movie that was maybe even bigger than the thing that it meant to be copying originally, which was Twilight, I think.
