This looks weird and interesting.
(I’m getting a bit of a weird 70’s sci-fi film vibe from it all as well. Or is that just me? Obviously SW is from the 70’s, but I’m thinking pre-SW sci-fi films. The sets and locations seem more odd and colourful than what we’ve seen before in SW.)
It’s a Dr. Ball convention! 😉
Seriously though, they do resemble the interrogation droid Vader used on Leia.
