Mel Gibson sorry for past controversial comments

London: Actor-director Mel Gibson is sorry for his behaviour over the last decade and regrets whatever wrong he has done in the past.

The 60-year-old star said keeping low profile was his way to deal with the erratic situation, reported Female First.

"I've done a lot of work on myself these last 10 years. I've deliberately kept a low profile. I didn't want to just do the celebrity rehab thing for two weeks, declare myself cured and then screw up again.

"I think the best way somebody can show they're sorry is to fix themselves and that's what I've been doing and I'm just happy to be here. He who tries, gets. If you try, you get somewhere," he said.

The "Braveheart" star's public image reached rock bottom when he hit the headlines for making misbehaving with a female police officer and having domestic abuse claims made by his ex-partner Oksana Grigorieva.

Gibson was also arrested for driving under the influence after he was caught speeding with an open container of alcohol in Malibu.

When asked what he learned from his mistakes, Gibson said, "I've learned a lot of things, like how to use my 'indoor voice'... And if you're going to drink, don't talk. Have a designated talker. Nobody has ever said to a drunk person, 'That's a brilliant thought! You need to share that with the world!"
