In a bunch of kung fu movies, there's this very specific trope, of this one dude who's watching the fight and explaining the styles being used to his fellow audience members.
Functionally he's basically a Mr. Exposition, but he always kinda comes off to me a bit like a sports color commentator, and I really wonder whether the vibes of each influenced the other.
@[email protected] In Jackie Chan's Gorgeous the character in this role actually states he's now a commentator for sports matches; he likes being behind the microphone because with his knowledge from training 'he sounds like he's invincible' but he fell so far behind the lead character's skills he now hires people to fight him and comments on the fight instead of trying to fight him himself. So I think the film makers are pretty aware of the similarities!
