Nagini, who? If you’re not a Harry Potter fanatic then this news may not be big deal, but it’s been revealed that Claudia Kim’s character is a direct connection to the Harry Potter series.

More from Entertainment Weekly:

Until now, Warner Bros. hasn’t disclosed the name of the character played by South Korean actress Claudia Kim (Marco Polo) in the movie. Kim is none other than Nagini, a circus performer with a unique power who years later becomes Lord Voldemort’s trusty killer serpent and Horcrux.

In the new film, Nagini is a member of the traveling Circus Arcanus where she puts on a very convincing transformation act for muggles.

Check out the latest trailer for THE CRIMES OF GRINDELWALD, which opens worldwide in November.
