The Rinzler comic version of the 1974 draft made several arguable errors - for instance, George Lucas in 1974 almost certainly imagined Annikin Starkiller with dark hair (like Jeffrey Hunter in The Searchers, vs. blond-haired romantic foil Clieg Whitsun) and Prince Valorum as black (a literal “black knight” & a precursor to James Earl Jones’ Vader).
Right. It also adds a lot of unnecessary “easter eggs” from later SW movies.
I do like the comic, but it also feels too modern-looking to me, as opposed to what the film might have looked like if it had been made in the early 70’s. Though I can see why Mayhew made it the way he did since he basically had to interpret most of the designs from scratch. I image it would be easier to make adaptations of the later drafts look more authentically retro since at that point McQuarrie, Tavoularis, etc. had already established a “look”.
