Yahoo News How Fantastic Beasts 2's huge reveal was created
Note: Contains spoilers for Fantastic Beasts: The Crimes of Grindelwald.
It turns out that Fantastic Beasts: The Crimes of Grindelwald's huge reveal sequence was so secret, even the people working on it weren't aware of the full significance of it.
One of the key sequences of the sequel goes into the backstory of why Leta Lestrange is haunted by a vision of a cloth-wrapped baby sinking into the depths. All we know is that it's linked to the true identity of Credence Barebone, but everything is not as it seems.
As part of their work on the sequel, Rodeo FX crafted this crucial flashback and in our series of exclusive images, you can see how the sequence came together.
The sequence sees Leta swap her half-brother with another baby – who turns out to be Credence – on a stormy sea voyage, only for her real brother Corvus to drown.
We also get a glimpse at Leta's older half-brother Yusuf Kama who has sworn an Unbreakable Vow with his father to murder the person that the elder Corvus Lestrange loved the most.
"It took a while for the whole team to get to understand the whole plot of that scheme. It was really complicated in a way, it was even broader before. We were supposed to see Kama adding the Unbreakable Vow with his father, there was much more backstory to it," Rodeo FX's Arnaud Brisebois told Digital Spy.
"In a way, you’re not so much story-dependent, you just need to do your effects properly [so] it took a while for us to even understand the connections of all these characters together. I don’t think anybody would have been able to really describe what was going to happen."
Brisebois continued: "At a certain point, I got an updated cut with the sound and I took some time to digest the whole thing and then I’m like, ‘Oh I got it!’
"Everybody was thinking that Credence was the drowning baby, everyone was sure and he would be saved or captured by an Obscurus underwater or something, but his backstory was not the case at all. So it was a funny turn of situation."
Fantastic Beasts: The Crimes of Grindelwald is out now.
