I have good news and bad news.
The good news is that I have some details on where this fight is from.
The bad news is that I don't think it's going to help much.
This scene is from a Brazilian movie named
La riña (aka
Rinha and
Rinha: O Filme). I saw some promotional material about this one back when it was in development, and I was very excited to see the end result. Then the talk just fizzled out. I didn't even know it was released until years later.
The film revolves around some sort of pit fighting venue, as far as I can tell. The woman seen wearing leggings in this clip is featured in another fight in an empty swimming pool earlier in the film. From what I can tell, she doesn't do too well in the earlier fight, which is why she looks so beat up before this one even starts. I'm not sure if her first opponent is the same opponent seen in this clip or not.
Now, the bad news... I have had no luck finding a way to view this film, so I can't tell you anything about the quality or frequency of the female fights. Everything I said above was gleaned from the promotional materials I saw back then, which was little more than a few still images and some short blurbs.
So, I hope this helps those who are interested get a start on their search for more info about this film, but I fear it may actually just end up sending you on a wild goose chase.
If anyone does find anything more about this, though, I would love to hear about it.
