All of the OT movies were studio movies, he didn't start paying for the Star Wars movies himself til the prequels came along. Kasdan and Kershner both turned down offers to work on the prequels.
helpfully explains, this is incorrect. The first film was a studio movie; the other five were independently financed (except for some finishing funds provided by Fox for the first sequel when it went over-budget).
I agree. For all his talk for doing artsy stuff did he ever supported up an coming talented directors with his wealth?
Lucas donated $175 million of his fortune to USC, a major contribution that seriously renovated and updated the facilities and equipment there. I think that counts as supporting up and coming talent. I believe he also funds grants and scholarships for production students there.
