JK Rowling told fans to wait for a huge reveal in the new 'Fantastic Beasts' trailer and it confirms a major fan theory

Warner Bros.We finally know who Claudia Kim (right) is playing in ‘Fantastic Beasts: Crimes of Grindelwald.’

Warning: There are spoilers ahead for “Fantastic Beasts: Crimes of Grindelwald.”

JK Rowling promised fans a big reveal in a new “Fantastic Beasts” sequel trailer out Tuesday morning, and she did not disappoint.

The movie’s final trailer reveals early on that Voldemort’s beloved snake, Nagini, was once human.

We see Credence (Ezra Mileler) whisper the name Nagini before watching actress Claudia Kim turns into the iconic “Harry Potter” snake. In the books, Nagini eventually becomes one of Voldemort’s horcruxes.

Fans were floored by the reveal.


According to Entertainment Weekly, Kim’s character is a travelling circus performer who can transform from human to snake whenever she wants.

Kim kept the secret about playing Nagini for more than a year. When you meet her, don’t expect Nagini to be as ruthless and murderous as the serpent she eventually permanently becomes.

“You’ve only seen her as a Horcrux,” Kim told EW. “In [‘Fantastic Beasts’], she’s a wonderful and vulnerable woman who wants to live. She wants to stay a human being and I think that’s a wonderful contrast to the character.”

Some fans have been theorizing for quite some time that we may see Nagini in the “Fantastic Beasts” sequel this November. Rowling also confirmed Tuesday on Twitter Nagini is aMaledictus, not an Animagus, meaning Nagini has a “mysterious blood curse” which will eventually transform her into a snake permanently. The author said she’s been holding onto this secret for about 20 years.

And just in case you’re still making the joke that Harry Potter set Nagini free from a zoo at the start of “Harry Potter and the Sorcerer’s Stone,” Rowling killed that fan theory Tuesday morning.

“Fantastic Beasts: Crimes of Grindelwald” will follow Newt Scamander (Eddie Redmayne) as he goes abroad to stop Grindelwald (Johnny Depp) from gathering pure-blood wizards to rule over non-magical humans.

Another big reveal at the end of the trailer was Scamander’s brother, Theseus, a war hero and Auror. It appears he’ll help Newt attempt to take down Grindelwald.
