Here’s the dealie. Because I’m kinda in a “burn it down” mentality with regards to spec right now.
I think the “big IP” (house-wise) that keeps getting mentioned is Ghostbusters. When I was told the tentpole IP for the event was “bigger than Stranger Things,” my thoughts went bigger IPs to me. If I think about it from Universal’s perspective, Ghostbusters would be bigger than Stranger Things. Especially from a bunch of haunt designers in their late-thirties/forties.
Because we expect it, because most of us are a bit younger, because most HHN are horror fans, Ghostbusters doesn’t feel big. To us. But it is. It has a history at Universal, and is still widely loved. I can see Universal thinking it’s huge.
The rumor of a “big IP” has persisted. But nothing bigger than Ghostbusters (or arguably Universal Monsters) has been float or hinted at.
