Since he's had a long and productive and successful career, and a good longterm marriage and what seem to be a lot of good kids, I have to think that he may just have some very bizarre affects, but is not actually bizarre.
I know what you mean. I actually think that he is nervous talking in front of a "live" audience
I would not label it a good longterm marriage. I would label it a marriage that survived his sins. We don't need to go further than he did in the interview.

I want Mel to do well. I want him to be a good man, a good husband, a good father. "I just didn't want to go on," he told Sawyer.
"Everyone's got something," he added. "I would get addicted to anything, anything at all. Okay? Doesn't matter what it is drugs, booze, anything. You name it coffee, cigarettes, anything. Alright? I'm just one of these guys who is like that. That's my flaw.
"I checked into a few places, and sorted myself out," Gibson said. "I didn't make a big noise about it. There's no point in doing that. You know? I mean, the real medal goes to my wife, who's a wonderful woman."
At his lowest, Gibson said he considered jumping out a window.
"I was looking down thinking, 'Man, this is just easier this way,' " he said. "You have to be mad, you have to be insane, to despair in that way. But that is the height of spiritual bankruptcy. There's nothing left."
The "spiritual bankruptcy" led him to reexamine Christianity, and ultimately to create The Passion of the Christ "my vision with God's help" of the final hours in the life of Jesus.
"I just didn't want to go on," he told Sawyer.
