The trailer for “Fantastic Beasts: The Crimes of Grindelwald” has premiered, bringing up many discussions and controversies in the Harry Potter fandom.

The trailer begins by setting the scene with beloved Hufflepuff and Magi-zoologist Newt Scamander in Paris, receiving information about a safe house he may need down the road, hinting at impending danger and conflict.

The following shots show Gellert Grindelwald (Johnny Depp, “Murder on the Orient Express”), Credence Barebone (Ezra Miller, “Justice League”) and Tina Goldstein (Katherine Waterston, “Logan Lucky”) from the previous film, guaranteeing they will all be tied into the sequel in some way.

Perhaps the most shocking part of the trailer was a short clip where viewers saw a women transform into Nagini, Lord Voldemort’s pet snake throughout the Harry Potter series. This shot changed everyone’s perception of Nagini and revealed that she is a “maledictus,” meaning shape-shifter, and was cursed at one point to remain in a snake’s body.

After the trailer dropped, many fans questioned the casting and whether there were racial prejudices in it, as the woman playing the human form of Nagini is South Korean actress Claudia Kim (“The Avengers: Age of Ultron”). She is one of the only women of color in the entire franchise. Many felt this was not the best way to represent women of color, as they felt Nagini is akin to a slave.

Author J.K. Rowling defended her choice, saying she based Nagini on a snake-like creature from Indonesian mythology, and Indonesia includes hundreds of ethnic groups. Fans fired back, as actress Kim’s ethnicity is not included in those groups, and accused Rowling of trying to interchange Asian ethnicities.

The rest of the trailer mainly shows Grindelwald casting spells and attempting to use magic to eliminate the peace between the wizarding and muggle (or “no-maj,” as the American wizards say) worlds, which seems to be the main plot point of this film.

Many Harry Potter fans were also excited to see a young Albus Dumbledore, played by Jude Law (“King Arthur: Legend of the Sword”) in the trailer, though he is only on screen for a few seconds. The trailer made it seem like stopping Grindelwald laid mainly on the shoulders of Scamander, so it is unclear how Dumbledore will help, if at all.

Many were also pleased to see the muggle character Jacob Kowalski (Dan Fogler, “Take Me Home Tonight”) in the trailer, as the first film left it unknown whether he would return. His and all the other muggles’ memories were wiped following his adventure with Newt, Tina and his own love interest, Queenie (Alison Sudol, “Between Us”), who also doubled as his love interest. However, it was not fully explained whether Jacob’s memory was completely gone, as he kissed Queenie under her magic umbrella, thus being protected from the memory-wiping rain for a short time. The trailer does not explain what happened to Jacob, but viewers can assume the film will.

Also introduced in the trailer was Leta Lestrange (Zoe Kravitz, “Kin”), a former friend and potential love of Newt’s from his years at Hogwarts. She was mentioned in the first film, but her role in Newt’s life was left more on the ambiguous side. In the first film, Newt still kept her picture with him and hinted that their relationship did not end well.

The film comes out Nov. 16, and is expected to have as much, if not more, success than the first film.
