I duno. MJ was definitely a recluse. He pretty much never gave an interview until the early 1990s, and then it was only to clear his reputaion. Lucas is definitely NOT a recluse, though he was in the 70s and 80s. He seems unable to escape that reputation. GL and MJ have a lot more in common than people realize:

-Despite being regarded as reclusive, both are public figures

-Both are ridiculously wealthy

-MJ built Neverland Ranch, GL built Skywalker Ranch

-Both had their heyday in the 1980s

-Both are protective of their private life, and have a mysterious aura to them

-Both are among the most influential and successful artists in their fields, and both got famous at a young age, with scandal following them in the 1990s

-MJ in his recluse went a bit crazy and re-constructed his face. GL in his recluse went a bit crazy and re-constructed his films.

-Both have fans that either hate or have mixed feelings about them for their personal decisions, despite admiration for their early artistic efforts

-Both see themselves as, and to some degree actually are, misunderstood by the media

-Both of them had/have their contributions overshadowed by their failures at the end of their lifetimes

Of course, there are many huge differences. But while GL does indeed have a lot to be proud of in his life, ever since 1999, his reputation definitely has been mixed, much like Jackson since the early 1990s.
