“The American illustrator Ralph McQuarrie and British sculptor Brian Muir are the two guys who made this character design in 1976 for the Episode IV of this famous space saga.” Minor nit. At the time of writing, Lucas had no intention of making Star Wars more than a single film. That came after production started. I forget my source for this but I think it’s either Robert McKee or Blake Snyder. And there’s some confusion around this due to a backdated screenplay with the Episode IV title.
