"I can't move against Grindelwald", Dumbledore tells Newt. Anyway, the first trailer for the sequel to Fantastic Beasts and Where to Find Them, which grossed over $800 million, was light on plot, but not the SDCC teaser.
Fantastic Beasts films showcase a new protagonist - Eddie Redmayne's Newt Scamander, along with Jude Law's young Dumbledore, who together face Depp's villain. He went on to call Crimes of Grindelwald "possibly the darkest" of the franchise.
Fantastic Beasts: The Crimes of Grindelwald is being directed by David Yates, from a screenplay by J.K. Rowling, and produced by David Heyman, J.K. Rowling, Steve Kloves and Lionel Wigram.
Then, in some sort of staged surprise, Depp strolled out in full costume, bleached hair and all, as the dark wizard himself.

But it is the nod to the Deathly Hallows that's likely to get them the most excited, as the Elder Wand is briefly seen in Grindelwald's possession.
The film features an ensemble cast led by Eddie Redmayne, Katherine Waterston, Dan Fogler, Alison Sudol, Ezra Miller, Zoë Kravitz, Callum Turner, Claudia Kim, William Nadylam, Kevin Guthrie, Carmen Ejogo, Poppy Corby-Tuech, with Jude Law and Johnny Depp.
As for being dubbed young Dumbledore - or as moderator Aisha Tyler referred to him, "Hot Dumbledore" - Law revealed he is a "very spritely" 45.
The most surprising appearance is that of Alchemist Nicholas Flamel, the creator of the Philosopher's Stone, the item of great value to Lord Voldermort in the first Harry Potter book, who has an amusingly awkward encounter with Jacob. What about Depp's involvement in the film and the panel? While I'm still not sold on Jude Law as Dumbledore, the rest of the cast looks wonderful.
