That’s interesting how Obi-Wan was intended to be older. It sort of reminds me of Aragorn. Ewan McGregor did a good job in the role, but it was an odd choice for George to cast someone so young.
I do wonder what George was picturing when he thought of the Clone Wars. I suppose he just came up with the name as a way of intriguing the audience with unseen backstory, giving us a sense of some crazy wars off in space back in the olden days of the Republic. And when the time came to write the prequels, he had to figure out what the term “Clone Wars” actually entailed. I doubt he intended back in the 70’s for the clones to be the army protecting the Republic. I do wonder, though, at what point he came up with the idea that the Clone Wars were orchestrated by the Emperor to gain power, since there’s nothing to suggest that in the OT. Maybe originally, the Clone Wars were just a series of conflicts unrelated to the rise of the Empire, which just happened to occur around the same time.
