Sometimes I find it hard to tell who has stepped off a movie or TV set and joined the Parade of Wonders. Some cosplays just look that authentic that they could be used in a real production. I know the Star Wars movie Rogue and the Mandalorian one actually used some members of a cosplay group to play Stormtroopers.
For me, the novelty of seeing so many characters in one place never wears off. I think black and white makes it seem even more real to me as I start to notice all the extra little touches people use in their cosplays that make them feel real.
