Beyond criminal and civil problems, Gibson's now public rants could spell the end of his Hollywood career. He survived his last public relations nightmare four years ago, but this one could prove too toxic even for Hollywood.
When Gibson's last scandal involving an anti-Semitic rant made headlines, his film "Apocalypto," which he directed, was scheduled for release. This time, Gibson has another film waiting in the wings. But now, he's the star.
In "The Beaver," Gibson plays a loner who talks to a beaver puppet on his hand. It's a quirky independent film that has long been a "passion project" for many in Hollywood, according to the Hollywood Reporter.
Jodie Foster, who directed and co-stars in the project, brought her friend Gibson on board. "Twilight" producer Summit Entertainment, which signed on as distributor, planned to release it later this year, rolling it out for the fall festival circuit.
The fate of the film remains unclear, notwithstanding the potential awkwardness of publicizing a film with "Beaver" in the title and Gibson as its star.
PR guru Howard Bragman told "GMA" that Summit is "stuck with this film, and I don't think they know what to do with this thing."
But Bragman doesn't believe anyone should feel sorry for Gibson.
"Let's not feel really bad for Mel Gibson," he said. "He's reportedly worth more than a billion dollars."
Even so, he'll have to find another agent to represent him. Since Gibson's agent Ed Limato, who also repped Kevin Costner and Denzel Washington, died, he has been dropped by Ari Emanuel's William Morris Endeavor Entertainment.
"It's hardly surprising," Bragman said. "First of all, Ari Emanuel was one of the first people to criticize after his anti-Semitic remark in 2006. There was no love lost there to begin with."
But as audio recordings of his rants continue to leak, Gibson will have bigger problems than his career. Bragman believes the actor-director should be more worried about "possibly going to jail" than his reputation.
"I think a lot of this is going to leak out," he said. "I don't think this is over for Mel. Being quiet is probably the smartest PR strategy that he can do."
