NEW YORK (TheStreet) -- Did you know that Hollywood's richest movie moguls collectively control more than $20 billion of personal wealth? That's a big bankroll no matter where you are. 

Leading up to this year's Academy Awards, set to air on Sunday, Wealth-X, the Singapore-based high-net-worth intelligence firm, put together a list of the richest producers and directors in Hollywood.

While American Sniper-director Clint Eastwood didn't make Wealth-X's list, plenty of other well-known directors did.

At the top of the list is George Lucas. The director and producer of the popular Star Wars franchise has an estimated net worth of $5.4 billion, though Wealth-X notes that the sale of LucasFilm to Walt Disney (DIS) - Get Report in 2012 for $4 billion contributed to that. Wealth-X also notes that Lucas, 70, directed only six feature films during his career, four of which were Star Wars installments.

On the other hand, Steven Spielberg, who ranks No. 3 on the list, has directed more than 30 feature films, including classics such as ET, Jaws and Jurassic Park.

Check out who else made the list. And when you're done, be sure to check out how other Oscar-nominated movies fared at the box office.
