I speculate it’s closer to 100.
A&D is about 15 people by itself. Let’s say 5 people each know in Make-up, Costuming, and Tech know within Entertainment. That brings us to 30. Outside of Entertainment, Legal, elements of Marketing know (so another 10), and executive management knows/has access to the line up. So, there’s probably around 50 within Universal.
But... Universal only works with 2-3 companies for builds, and those organizations chat. So, the foremen likely know the lineup, and some of their workers will know. So, let’s say, 60 from there.
Then, there’s chatter. A&D and Creative will chat, so people in Creative will know. Family members will know.
I’m expecting closer to 100.
