(CNN)Almost 20 years after the first book was published, Harry Potter mania seems in no danger of waning.
Trailer for Harry Potter spinoff 'Fantastic Beasts' released
There's a theme park that opened last week, and on Sunday, the first full trailer for the Harry Potter prequel "Fantastic Beasts and Where to Find Them" hit the Internet with a magical touch.
To unveil the trailer, Eddie Redmayne, who stars in the film, popped out of a suitcase on stage at the MTV Movie Awards.
The new movie, based on the "Harry Potter" series written by J.K. Rowling, follows the adventures of writer Newt Scamander.
The film explores New York's secret community of witches and wizards decades before Harry Potter is born, in the 1920s.
It follows a Hollywood trend of making serialized spinoffs and prequels such as "The Hobbit," "X-Men" and "Star Wars."
Potterheads buzzed with excitement; the last Potter film was released five years ago.
But the trailer also prompted some fans to question the film's diversity.
The film also stars Colin Farrell, Jon Voight, Ezra Miller and Samantha Morton.
"Fantastic Beasts" hits theaters November 18.
