Whitewashing is a casting practice in the film industry in which white actors are cast in non-white roles. As defined by Merriam-Webster, to whitewash is "to alter...in a way that favors, features, or caters to white people: such as...casting a white performer in a role based on a nonwhite person or fictional character." According to the BBC, films in which white actors have played other races include all genres. African-American roles and roles of Asian descent have been whitewashed, as well as characters from the ancient world in the genre of classical and mythological films.
