I know it existed as recently as 2006 because there was an awesome reality series on A&E about the TXRD. It looked a lot like the movie with matches held in an old warehouse which looked like a serious fire code violation. You're right, all the videos today look like they're in a proper sporting arena. If you can get your hands on the A&E series "Rollergirls" I think you'll really like it. It features the real Holy Rollers and Hurl Scouts as well as a bunch of other teams. I'm sure "Whip It" was really influenced by that show.

Thank you! Looking "like a serious fire code violation" sounds wild enough. :-D I think I'll find the series anywhere, already found something on vimeo, but it was in French.

I know, I had to ebay it myself, but I think it's worth owning! Each episode has the same basic structure: the first half is some random life drama between the girls, and the second half they strap on some skates and pummel the living snot out of each other. Truly a masterpiece of tv 😂
