Rollan is Native American. For starters, Amaya is the Americas. Secondly, on the covers of the books, Rollan often wears a scarf thing that may look like is based on traditional Native American clothing. And thirdly, the main four are meant to come from different lands, and are different races. Conor is white, Abeke is black, Meilin is Asian, and Rollan would be Native American.
And casting a white person as Rollan, a Native American character, is quite racist.
In the history of film, most actors have been white. And even when there are people are color, most of the time, white people are their actors.
Take the movie The Last Airbender. Yeah, we all know that movie was bad, but it is such a good example of whitewashing. In the original show, each element in the lands were a different race. Yet, in the movie, all the characters were WHITE. Except the villain, yeah, we have to make the villain not white, totally. No wonder this film was said to be the worst movie of the time.
And even the upcoming movie, The Ghost in the Shell. It was based on a manga, and I think it's about this robot girl. The robot girl is Japanese. And guess who they casted to be her in the movie? If you guessed a white person, good for you! But not good. What is annoying is that the producer of the movie said that the main character may be whitewashed, but the other characters will be more diverse. Yeah, sure, let's have the white person be the lead role. Because white people should get the best parts.
Also, hey, Hunger Games fans! Did you know that in the books, Katniss was described to have olive skin? And white people usually do not have olive skin! Whoa! The more you know! And did you know that during the casting of the movie, they would only let white people audition for Katniss? Yup, it wasn't that Jennifer Laurance was the most talented as Katniss, it was that she was the most talented of the white people! So you guys should stop saying it was only because she was better, because it wasn't like that!
Sorry I'm ranting. Just speaking the truth.
