GEORGE LUCAS: FILM MAKER/ PRODUCER – $5.5 BILLION
One of the richest Americans, George Lucas managed to amass this huge amount of wealth by making films. He is best known for Star Wars and Indiana Jones. His movies did amazingly well in the box-office, some of them are on the list of 100 highest grossing movies of all time. In 2012, he took retirement but has been working on and off and consulting whenever he is needed. His house is rightfully called the Skywalker ranch after the Skywalkers from Star Wars Trilogy. It is said that Lucas built it up over the years, and it has cost him close to $100 million. His car collection is huge, too. Apart from having all kinds of luxury cars, he owns the first Darth Vader car. It somehow looks like Darth Vader, hence the name. It is Mosler MT900S, comes with a price tag of $203,000.
