There’s one major difference between Mistborn and Game of Thrones, pointed out by Brandon Sanderson, that could indicate something about how his books should be adapted. George R.R. Martin’s A Song of Ice & Fire novels are some of the most prolific fantasy books ever written, and given the popularity of the HBO adaptation, they’re a common comparison point for any series hoping to be made into a film or television show. Brandon Sanderson has long discussed the possibility of a Mistborn movie adaptation, and there’s much to theorize about regarding how that would look.
