If which movie does Audrey play a Native American? I have heard people say that she did, but I don't know for sure.

The movie was called "The Unforgiven", and I have watched it. She played a Native American in it, but it was somewhat hard to believe because of her European accent. Here is a picture of her in the movie.

I think its called Green Mansions. I don't know, I have not watched it either.

It's probably in one of her older movies, te might want to check out the black and whites she did, probably before Roman Holiday.

She played a Native American in "The Unforgiven," which was made in 1960.
