17 Revelations About Fantastic Beasts: The Crimes of Grindelwald, Straight From the Set

Both new and old creatures will pop up on screen during the sequel, but if you're wondering which Eddie Redmayne is most excited about, wonder no more: baby Nifflers.

"It's probably been my favorite scene to shoot so far, the baby Nifflers. They're just causing havoc, and it coincided with the time that I have a 15-month-old child, and the baby Nifflers retain many of the qualities of my 15-month-old," he laughed. "It's been wonderful. It's so lovely because you have the [visual] effects department, who are sort of actors in themselves, coming up with ideas. You then have Jo's book and how she imagined them . . . it's such a collaboration of different spirits."
