I'll assume you're serious, considering you're not from the US. Jimmy Fallon is a late-night talk show host that does nightly shows on the NBC television network, which is under the same corporate umbrella as Universal.

Thanks for the info guys. I'd never heard of Jimmy Fallon before yesterday as he definitely isn't a household name in the UK and Europe. With that in mind it will be interesting to see how Universal markets this attraction internationally? I can't remember the last time Universal opened a bad attraction, so no doubt this will be amazing!
