The documentary was about Cathy "Cat" Davis' boxing career, and it also had many interviews of other persons.

Muhammad Ali and Joe Frazier were interviewed and asked their opinion about women's boxing.

I was surprised to hear their responses, considering that they were given the opportunity to do what they loved to do--- which was "box." Joe Frazier was the first to comment on how he felt about the sport. 

Frazier's Comments: "Well, I would just "LOVE" to see the girls get into the 'sports' --maybe that would straighten out some of the situations that they have. Because women think that they can do being the things that "Men's" can do, but I don't really think so...."  

Muhammad Ali's Comments: "Women are not made to be hit in the breast, and face like that... the bodies not made to be punched right here (Ali pats the breast area of his chest). Get "Hit" in the breast..... 'hard' ....and all that." 

The commentator then asks Ali about in spite of what he had just said about women's boxing, that what was his opinion of Cathy "Cat" Davis, a woman boxer who had 15 KO's and who was "prettier" than him.   

Muhammad Ali's Comments: "She?.....Is it a "She"?..... It's a she.. SURE it's a she?......I don't know her, not saying anything about her, I never heard of her. BUT, women who fight those type of physical sports, they do most everything like men...."    

Yes.... that was my favorite male boxer, Muhammad Ali, saying that about women's boxing when I was also struggling in the sport in 1978.

Documentaries often include interview clips or archival surveillance footage to tell a true story with a narrative structure. Home security cameras and CCTV cameras often catch evidence on film or record comments by people when they think no one is watching or listening.
