I suspect the big thing that’s always held Lois McMaster Bujold’s Vorkosigan series back from being made into a movie or television show is Miles being disabled. Peter Dinklage could’ve played him, but he’s too old at this point for young Miles. And there’s probably not a lot of acting talent with dwarfism AND the manic charisma that playing a proper Miles needs.
I wonder if it’d work as an anime though? Lois McMaster Bujold reviews a lot of manga on Goodreads so I imagine she might at least entertain the idea if anyone ever approached her.
I think her Chalion series would work as an excellent series of shows, either live action or animated. Penric is, personality-wise, a lot like Miles, but easier to cast.
