Why do you think that 2001 is so influential? Star Wars is definitely the archetypal quest myth- it has all the features including the maimed hero, as does Harry Potter, but so do many other novels and movies. 2001 may have influenced the setting by popularising the notion of science fiction film, but I think it had a different message entirely. While 2001 was a sort of history of humans of Earth and looked to its own future- Star Wars was set on 'a galaxy far, far away' and the action does not intend to apply specifically to Earth. This is important as imagination runs free in Star Wars, fantasy is given full flight and ideas are limited only by the budget!
