Joe Louis and Jack Johnson--film connection and context

The historical significance of these two men is important to our discussion topic, mainly Staples' question referring to Malcolm X's use of the term "Uncle Tom":
1. Jack Johnson was the first African-American heavyweight champion
2. He was very unpopular with white America because of his outlandish, rule-breaking behavior, and over-the-top persona and was non-apologetic about it
3. He dated white women and was eventually run out of the country
4. So, when Joe Louis became champion in order to alleviate the fears of having "another Jack Johnson," his promoters created an image that was the absolute opposite of Johnson.
