Firenado

Watching this now is it set in Texas am confused as half the cast sound English and some have really bad American accents!!! I love cheesy disaster movies so still plan to watch it even with the bad acting. One minute Anna sounds American, then English and then Scottish or Irish lol. The special effects are awful too but hey it's a disaster movie what do you expect. Even the number plates are British lol. Anyone know where it was filmed or where it's supposed to be set ? Same thing with the movie shockwaves filmed by the same people. Is that film set in usa or England. Looks like England but never mentioned and it's not like England is on the edge of a tectonic plate and even the scientists wouldn't or couldn't explain why lol.
