MANDO!!! This was essentially Mandolorian Season 3 Episode 1.
I'm not sure what I think about the space slaughterhouse. I'm guessing most of it was a virtual set. They got away with a minimum amount of sci fi cues, mainly the white tiles with black grout, some radiused doorways and windows, and a blueish cast to the lighting. And lots of aliens, of course.
Seems like most of the overtly sci fi elements were virtual, while most of the practical props and furniture were contemporary, and kept plain enough not to give off any real vibe of their own.
The slaughterhouse boss, Kaba Baiz, gave off really strong Brion James vibes to me, though the actor/stuntman playing him looks nothing like the late Brion James.
