This is from the movie, Avatar: The Last Airbender that is based on a show of which every single character is not white. The culture, the setting and the people were influenced and drawn as ethnically POC. But when it came to the big screen, all the characters save for the villain became white. The message here is: only good people can be white and bad people (enemies) are not white.
Other examples are: Dragon Ball Z live action movie where a white guy (Justin Chatwin) played a Japanese alien called Goku, the upcoming Ghost in the Shell movie where Scarlett Johanssen (a white woman) plays a Japanese cyborg and the upcoming Dr Strange movie where Tilda Swinton (white woman) plays a Tibetan monk
