This movie had to have come out in the late 1990's or sometime before 2007. I don't remember what it was about other than it was about some Native American Indians and I think one or more white or non-Indians. I am pretty sure this was based on a true story.

What I do remember about this movie is the funny scene at the end during the credits. The non-Indian person (I think a white guy but not sure) ends up taking the Indian Chief to a modern-day grocery store and the Chief does some really silly things because he doesn't quite understand the concept of a grocery store & using a credit card. I think this part was real actual footage.

I just remember this scene during the credits and walking out of the theater thinking, "Wow, that was a great movie!"

I really want to figure out what the name of this movie was so I can see it again.
