Extended 'Terminator: Dark Fate' Trailer Takes Us Behind-The-Scenes

I've done pretty well I think. I've avoided all trailers and potential spoilers for Terminator: Dark Fate, or at least I hope. However, I did check out the first minute or so of this new trailer which you can view below if you wish. It reveals some behind-the-scenes footage at the beginning of the trailer, I believe this was first shown at Comic-Con?

Anyway, it looks like there are some crazy cool stunt scenes, but I'm hoping that it isn't just style over substance. However I am pleased to learn that it will be rated R, so I'm interested to see where this one goes. Are you looking forward to the latest Terminator installment? 
Plot details are slim, but to be honest I haven't really tried to hunt them down as I'd like to go into this as blind as possible.

The film stars Linda Hamilton (“Sarah Connor”) and Arnold Schwarzenegger (“T-800”) Mackenzie Davis, Natalia Reyes, Gabriel Luna, and Diego Boneta. Tim Miller directs (Deadpool) while visionary filmmaker James Cameron and David Ellison produce.

The one spoiler that I did learn is that a previous actor is making a return, so I'll be interested to see how that turns out. Anyway, check out the new extended trailer below if you'd like.
