Here's a really not very good photo of one of my favorite effects, the actual flying monkeys that flew around the theater. I think they're balloon drones?
The photo is also not good because the seats vibrate, the air moves, it's really cool.

I went to The Sphere this morning to see The Wizard of Oz!
It was a beautiful tribute to the original, a spectacular show of immersive theater, and evoked some questions of how to extend and care for a beloved film as it becomes a BIG experience; there were a few rough bits, and lots of wonder.

It turns out it is, indeed, THAT "Ex Lax". And boy were they proud of it, as you can see in the signs from this 1956 photo in the NYPL collection by Max Henry Hubacher: digitalcollections.nypl.org/items/78a691...
And here's a 1949 photo with the arch: digitalcollections.nypl.org/items/bb5360...

London's Phantom Peak is an incredibly underrated immersive show!
It's like immersive theater meets LARPing meets a video game meets and escape room. Also, they have ice cream.
