Fantastic Beasts 2 spoiler warning: Eddie Redmayne begs fans to keep HUGE twists secret

The film, officially titled Fantastic Beasts: The Crimes of Grindelwald, is out next week and is rumoured to finish with huge revelations.

The reveal in the trailers of Claudia Kim as a human form of Nagini, it seems, was just the tip of the iceberg as far as shock Harry Potter twists are concerned.

In a video posted to the official Fantastic Beasts social media accounts, Redmayne said: “Guys, I’m holding a badge which is a hashtag to protect those damn secrets written on it.

“And please, I’m imploring you, if you go and see Fantastic Beasts: The Crimes of Grindelwald, there are a few Easter Eggs and spoilers that are so intense.

“Please, please, please don’t ruin it for others.

“So #ProtectTheSecrets and see you soon.”

Fantastic Beasts 2 has seen some early reactions land online, and it does indeed seem like it’ll be shock reveals that keep people talking.

“I watched the new #FantasticBeasts film for the second time already. It’s seriously SO GOOD!!!!! Lots of unexpected moments,” said one person on Twitter.

Another wrote: “Fantastic Beasts and The Crimes of Grindelwald is a magical must-see! It builds upon the original & is sure to delight Harry Potter fans.

“Remarkable visuals, engaging story, & an ending that will leave you speechless. Johnny Depp as Grindelwald is perfection. #CrimesOfGrindewald.”

However a third ranted: “FANTASTIC BEASTS: THE CRIMES OF GRINDELWALD is an erratic and overstuffed mess.

“The most egregious ‘fan service’ since Gandalf battled The Nine in THE HOBBIT, this is Rowling’s sloppiest and probably worst wizarding story. Few sequences aside, this is one dead hippogriff.”

Redmayne is back as Newt Scamander, with Katherine Waterston as Tina, Dan Fogler as Jacob, Alison Sudol as Queenie and Ezra Miller as Credence.

Claudia Kim is Nagini, with Depp as Grindelwald, Jude Law as a younger Albus Dumbledore and Zoe Kravitz as Leta Lestrange.

It has previously been said that as many as five Fantastic Beasts movies will be made.

Fantastic Beasts: The Crimes of Grindelwald is out on November 16.
