Am I wrong in thinking that most of the troopers we saw were probably Rogue One costumes?
Indeed, there were a lot of shore troopers at the Imperial facility. It’s not the first time the series recycles props, though. Multiple extras from TFA, Rogue One and Solo have made reappearances.
I actually think its quite neat that they’re reusing costumes for the movies. Not only is it nice seeing familiar uniforms, aliens, etc. but it’s fun to see that even a big show like The Mandalorian resorts to recycling props and costumes. Like Hal 9000 said earlier, there’s a certain charm to these simple and old school moviemaking shortcuts.
