Interesting Topic
It is easy to overlook the details of how ethnicity plays a role in determining which role a person plays in a movie. For me personally I don't often pay attention to details like that in movies, but once I actually think about it stereotypes do seem to have a substantial effect on characters in movies. I believe it would be useful for your wiki to use examples from popular movies to show to what extent the concepts of ethnicity and stereotypes are prevalent in the film industry. I am looking forward to reading the final product!
