The actor, who has made a comeback in recent years, was in Dublin for the premiere of Daddy's Home 2
Mel Gibson says light is being shone into "a lot of dark places" in Hollywood at the moment.
It comes amid allegations of sexual misconduct made against a number of high-profile celebrities in the wake of the allegations against producer Harvey Weinstein.
Speaking at the Dublin premiere of his new film Daddy's Home 2 last night, the star was asked by Newstalk Breakfast's Henry McKean about the current atmosphere in Hollywood.
Gibson said that he hopes there will be a positive outcome for victims of sexual harassment or assault who are now coming forward.
He said: "I think a lot of light's being shined into a lot of dark places right now - and rightfully so.
"It's tragic in a sense, because a lot of the poor victims have to relive it. [It's] torturous for them - but they'll get free by re-examining it."
Gibson's career stalled in 2006 when he was arrested for driving under the influence of alcohol, and was recorded making anti-Semitic remarks following the arrest.
After a half-decade off screens, Gibson has made a gradual comeback in recent years - culminating in several Oscar nominations, including Best Film and Best Director, for his most recent directorial effort Hacksaw Ridge.
Talking about his own comeback, he simply said: "You just don't stop breathing."
