I recently watched The Hateful Eight by Quentin Tarantino and became highly interested in his work. As a result I began researching his other films and came across a mashup interview featuring him in relation to Django Unchained. During this interview, he states:
There's only been five American movies, that have truly dealt with slavery in the western format...
Video starts at the point of reference for the quote.
I looked around but I couldn't find the movies he was referring to.
What are the five American western films that deal with slavery that Quentin Tarantino is referring to during that interview?
For the sake of being on-topic, please supply a link to Tarantino's list in your answer.
