Disney will buy LucasFilm for $4.05 billion
in cash and stock, the two companies announced Tuesday. By cashing out now, experts say the filmmaker has spared his family the need to pick up the pieces of his empire after he’s gone. It also allows him to focus his remaining years on his charitable endeavors — particularly Edutopia and the George Lucas Educational Foundation, which he founded in 1991. “I am dedicating the majority of my wealth to improving education,” Lucas wrote in 2010 (pdf) on GivingPledge.com , which invites the world’s wealthiest people to commit most of their money to philanthropy.
