I watched Comanche Moon last night, which of course starred Wes Studi. I say of course, because anything in cinema which portrays Native Americans must by law star Wes Studi. The films in which he has starred that center around Native Americans include Last of the Mohicans, Dances with Wolves, The New World, Into the West, Bury my Heart at Wounded Knee, and other movies I'm less familiar with, including three movies in production.
His most famous non-Native American role is in the phenomenal heist flick Heat, directed by Michael Mann. My favorite Studi role would have to be Magua from Last of the Mohicans, also directed by Mann. Magua really, really hated the Grey Hair.
