But the actor's personal fortune, estimated at close to $1 billion, will take a major hit, now that long-time wife Robyn Moore has filed for divorce.
"This could easily be one of the biggest divorce settlements in Hollywood history," said Los Angeles family lawyer Lynn Soodik, who's not involved with the case. "Any attorney would advise her to take half."
Gibson's estimated assets include:
Over $600 million grossed by The Passion of the Christ;
$100-plus million in real estate investments around the globe;
$75 million for film and TV projects on which Gibson served as executive producer.
Robyn could also have rights to any of Gibson's future earnings.
Still, friends say the pair will go through the proceedings in an amicable, respectful manner.
"This divorce will probably reach a settlement in a matter of months," Soodik said. "It likely won't be messy since there's enough money to go around."
