I would like to add to this that the Annabeth and Grover casting for Percy Jackson are something I’m super happy and excited about, but there’s the difference here that in the original Eragon movies Everyone in Eragon’s family was made white, and all of the characters are at an age where it’s a lot easier to find good, practiced actors. Additionally, with Percy Jackson it’s giving more people, and specifically kids and young teens, an opportunity to see themselves as brave heroes, while with inheritance they whitewashed the whole main family, even though you might be able to get a Lot more out of The Inheritance Cycle with a book accurate casting, similarly to Annabeth being underestimated because she’s a black girl making more sense and a better story than Annabeth being underestimated because she’s a blonde girl.
For example, Sloane might not have liked Roran as a potential son-in-law not just because his family lived outside the town and Garrow thought it wasn’t worth teaching the boys how to read, but because Roran looked different too. And we already know Sloane is a bit Xenaphobic from the way he treats the elves when they’re taking care of him, so it wouldn’t really be surprising to find out he’s racist too. Thankfully Katrina’s a bit nicer.
Roran rising into leadership after the Ra’zac destroy Carvahall, being seen as the kind but dangerous warrior and leader but also essentially sassing everyone he fights, I dunno whether or not that’d be a big thing from what I’ve seen of Bollywood (which admittedly isn’t much, just posts from other folks) but it isn’t the typical American depiction, and also he’d totally vibe with Percy. Like imagine if the super powered but untrained twelve year old who’s primary weapon is a pen met this untrained seventeen year old who chose his weapon, a hammer, based on a legend because the guy in the legend got to retire- sorry that’s way off topic, but seriously it’d be so full of sass. Also they’ve both fought monsters and won despite their minimal training(Ra’zac, everything that Percy has dealt with)
Nasuada might have favored Roran(in a “uh your bride doesn’t have a dowry and she feels ashamed for it? She can have mine she’s clearly important to you if you’re marrying her, she doesn’t deserve that guilt” kinda way) not only because he’s an insanely powerful warrior and brother of Eragon, the only free dragon rider she knew of, but also because she saw right of they had a similar difference from most of the humans in their region, her being black and him being brown. It would also explain further Eragon’s own interest in Nasuada in opposition to a recoil at something that would seem strange and foreign if Allegaesia were mostly white(which I’m not sure it is, I’m just going off what I know of of Carvahall’s demographic and scaling up), instead he’s just really interested because, “hey, look, she’s colored too!! Maybe she’s not brown like me, but she’s not white like everyone else.”
It might also be the case that Eragon went to Brom when he had free time not only because he’s the old storyteller, but he’s the old storyteller who looks like Eragon and has similar cultural differences as Garrow, and therefore Eragon and Roran. It’s stated clearly when Eragon is training with Ormoris that Brom was made fun of because he acted differently than the other dragon riders he trained with, so if Garrow had similar cultural differences and passed them down to his son and nephew, then Eragon might have picked up on Brom’s similar differences and gotten more attached to him because of that.
Idk, it’s just really cool to think about how Carvahall is mainly white and how characters who by their descriptions or their relations to others aren’t white and how that might affect them and how they interact, and the movies from way back kinda messed that up. It also provides tons more representation and an element of realism if they relate it to the plot, which they wouldn’t have to for Eragon’s family, but the books already did for Nasuada with the Trial of the Long Knives.
Please let me know if I’ve said anything offensive or rude, these are just my opinions and speculations but if there is anything rude about them, let me know, I’m always trying to grow and I could’ve messed up in a ton of ways while writing this as a white person.
