Crystal Films is another venerable fighting promoter still alive and well, although I have not seem a huge flow of productions lately. Despite some trials with other genres they are basically a cage of cats. In the later years, most videos are in a category I call "in-house street fighting": plain girls in plain clothes try to tear off each other garments and to broke some ribs as well. If there was a script, those ladies certainly forgot it. Fighting scenery is your neighbor´s living room.
Much more interesting were the Hellfire Club productions, shot in some New York City basement in a 6 x 6 foot ring. Genuinely raunchy, club fights usually finished with the girls naked and bruised.
All Crystal Films productions are available at its site here.
