Author JK Rowling has defended the decision to cast Korean actor Claudia Kim as Voldemort’s devoted pet, Nagini, in ‘Fantastic Beasts: Crimes of Grindelwald.’ In the final trailer of the film, starring Eddie Redmayne, Jude Law and Johnny Depp, Kim is shown transforming into Nagini, who is later revealed to be one of the Dark Lord’s Horcruxes in Rowling’s Harry Potter books. The casting drew the ire of many on social media for being racist, while some called it a classic case of Asian actors playing submissive characters on-screen.
