GrittyLipids, Off the top of my head I don’t remember how much the book of #Dune talks about the Harkonnen use of gladiatorial combat, but the movie draws a relatively subtle link between their idea of it and bullfighting - the guys in the wide black hats are like picadors, who stab the bull with lances to weaken it. I’ll avoid spoilers on a 60-year-old book or the new movie, but it’s a fun subtle thing.
