The newly released trailer for the upcoming film revealed Claudia Kim, a South Korean actress, will be portraying Nagini, a snake who serves as a slave to the villain Voldemort. One of the biggest reveals from the trailer is that Nagini, Voldemort's serpent from the original Harry Potter films, is a maledictus, or a human woman cursed to transform into an animal. Personally, I don't think this is a problem and think it's good to give a more representation, especially when it's clear the fate of the character is linked to the culture being represented. But suddenly making Nagini into a Korean woman is garbage.
Though Potter mastermind J.K. Rowling (also the screenwriter of this film) was excited for fans to hear the name and put things together, the reaction to it has not been very positive. Kim was able to break her silence about her character thanks to this new trailer and shared some more details in an interview with EW.
And that led many fans to wonder: just how long had J.K. Rowling been keeping this a secret?
Kim further explained that due to Nagini's mysterious blood curse she knows that eventually she'll become a snake permanently.
Had Harry Potter arrived in the 80s, there's every chance the part of the boy wizard could have been snared by Macaulay Culkin.
Also, the EW article linked above says Nagini "has powers like wizards have".
But JK Rowling tweeted that Nagini is based on "the Naga", which are "snake-like mythical creatures of Indonesian mythology". "Don't we want people to do better?" said another tweeter, Simen Sund, whilst Harun Wijanarko defended the author's autonomy over her own universe. You've only seen her as a Horcrux. To foil Grindelwald's scheme, Albus Dumbledore (Jude Law) enlists his former Hogwarts student Newt Scamander (Eddie Redmayne, reprising his role), who may not be fully aware of the dangers he faces.
The nearly two and a half minute trailer promises action, surprises, wondrous visual effects, a strong Dumbledore/Newt bond, and a terrifyingly motivated villain in Johnny Depp's Grindelwald.
Fantastic Beasts: The Crimes of Grindelwald will be released worldwide on November 16, 2018.
