NBCUniversal lit up the skies above Orlando on Wednesday with fireworks, flames, water, and drones, in what it called (in understated fashion) a "celebratory moment" for the grand opening of its newest multi-billion dollar bet: Epic Universe.

Epic Universe, the first major new theme park in the US in 20-plus years, is opening in Orlando, Florida, on Thursday. Fans are expected to camp out overnight ahead of the official opening day.

Thursday marks the launch of the first new major theme park in Central Florida in nearly 30 years—and it’s a big deal for NBCUniversal, the state of Florida, and theme park lovers across the country.
