I mean, I suppose Diagon Alley is just beautiful sheds...
I was dismissive of the idea Universal would be interested in a UK park anyway, but I was going through old online seminars and I stumbled on one from 2013 about the Harry Potter Studio Tour. In the Q&A at the end someone in the audience states they looked at the location the tour uses for a "Universal Studios location". I didn't even know Universal had actually properly looked at doing a park over here, let alone at a location a mile from my front door. Sounds like the main problem was the local council and access too, to think what could have been! Anyway, here is that Q&A, suppose it makes the idea of them taking over the Paramount Park project a bit more possible.
