Gibson presented the best director award at Sunday's Golden Globes
Mel Gibson says he has been made stronger by the "public humiliation" of his drink-drive arrest in 2006.
Gibson's arrest sparked outrage after a leaked police report quoted him making anti-Semitic comments to the arresting officer in California, who was Jewish.
"You ask anybody what their number one fear is and it's public humiliation," he told the UK's Mirror newspaper.
"Multiply that on a global scale and that's what I've been through. It changes you," he added.
But the Lethal Weapon star was philosophical about his troubles, saying: "What doesn't kill you makes you stronger. It's really that simple."
"You can't do anything but live in the moment and leave the future in the hands of providence and don't regret the past too much. Maybe just take a lesson from it."
Gibson's conviction for drink-driving was erased last October, after he successfully completed probation.
The actor had been ordered to perform public service work and attend Alcoholics Anonymous for three years.
He has reportedly given up drinking entirely since his arrest.
But Golden Globes host Ricky Gervais made a dig at his expense during Sunday night's award ceremony, joking: "I like a drink as much as the next man... unless the next man is Mel Gibson."
The 54-year-old took it in his stride, pretending to slur his words as he took to the stage to present the best director prize.
Gibson will return to UK cinemas later this month, playing his first on-screen role in eight years, in political thriller Edge Of Darkness.
The star, who won a best director Oscar in 1995 for Braveheart, is also preparing to film his own screenplay, How I Spent My Summer Vacation, in Mexico.
The movie, which tells the story of a career criminal who is arrested and placed in a tough prison, has caused upset in Mexico after plans were announced to move inmates from a real-life prison to allow filming to take place.
Hundreds of people demonstrated outside the Ignacio Allende prison in the Gulf coast city of Veracruz after learning their relatives would be transferred, making visits more difficult.
Gibson told the Mirror he had not requested the prison to be emptied.
"No-one asked for them to be transferred," he said. "It was a decision by the Mexican authorities."
