Arnold Schwarzenegger

One of the highest paid actors in Hollywood history, Arnold Schwarzenegger has earned some $500 million (before taxes and fees) in paychecks and profit-sharing deals from his movies.

He's made even more from early bets on everything from California real estate to stakes in some of the world's most valuable brands.

One of his best bets: Buying a minority stake in fellow billionaire David Booth's Dimensional Fund Advisors when it was managing $12 billion in assets.

Founded in 1996, DFA now has $777 billion of assets under management.

Other valuable investments include a piece of Easton Town Center, the Columbus, Ohio mall created by billionaire Les Wexner, and equity in the Waldorf Astoria hotel in Los Angeles.

Today, Schwarzenegger continues to own several businesses: film and production company Oak Productions, Fitness Publications Inc and film and trademarking holding venture Pumping Iron America.
