Momoa, an only child, was born in Honolulu, Hawaii and raised in Norwalk, Iowa by his mother. His father was a Native Hawaiian and his mother was of German, Irish, and Native American ancestry.
Comment: Momoa looks like one of the phoniest "Indians" ever. Let's put it this way: He makes Iron Eyes Cody look good.
This clip is riddled with racist stereotypes, of course. Ironically, it comes from an African American movie. Does the next scene feature an Uncle Tom shucking and jiving and eating watermelon? Somehow I doubt it.
