When it comes to making a mint from movies, few hit the big time. But with the right combination of a great story, acting talent and, crucially, the right funding—some people get very, very rich indeed.

Ultra-high net-worth intelligence firm Wealth-X has released a list of the American film industry's richest individuals.

"Certainly the list is a veritable cinematic Mount Rushmore of some of the most notable producers/directors and tastemakers of all time," Paul Dergarabedian, senior media analyst for Rentrak, told CNBC.

The producers and directors on this Hollywood Rich List control more than $20 billion of personal wealth, according to the research.

Here, CNBC takes at look at Hollywood's top movie moguls, ranked in terms of wealth.
