Question: are they really speaking lakota in westworld?
Answer: Lakota and Standing Rock Sioux actor Zahn McClarnon portrays the character Akecheta on HBO's “Westworld.” ... Episode Eight, “Kiksuya,” was largely subtitled, and McClarnon has said not only did the writers ask him to speak Lakota, a language he grew up around, but they insisted on it being as authentic as possible.
