Michael Moore is a controversial documentary filmmaker with a net worth of $50 million. Moore's biggest three movies; Bowling For Columbine, Fahrenheit 911 and Capitalism A Love Story have earned over $300 million at the box office.
Fahrenheit 911 raked in $230 million in theaters and another $3 million in DVD sales. After the theaters take their traditional 50% cut, that leaves roughly $130 million. Take away marketing, production and distribution expenses and Moore is conservatively left with $80 million. Moore was able to secure a deal from Miramax which guaranteed him 27% of his film's net revenues, or roughly $21.6 million. Michael also was entitled to 50% of the profits of Sicko which are estimated to be $17 million.
Moore is the author of several best selling books and received a $1 million advance for "Dude Where's My Country" plus a generous percentage of the book sales.
Moore financed his first documentary Roger and Me by holding neighborhood bingo nights around his hometown of Flint Michigan. He eventually sold the documentary to Warner Brothers for $3 million.
