Sorry, that doesn’t really fly, Star Wars was never “known for its originality.”
You’ve got to be joking. Star Wars was the first movie of it’s kind. It doesn’t get much more original than that.
You should see the letters column of magazines like Cinefantastique back in 1977. Lucas was accused of ripping off everything from Lensman to Dune.
Back then you really had to be ticked off to write a letter and lick a stamp. 😛
