Reflecting on his appearance on the show one night last November, Green says: ''I am the biggest critic of Trisha and Kilroy. You know - talk to a therapist rather than a TV audience. And there I am with eight million viewers tuning in to me talking about my violent father.''
What Green didn't reveal on Parkinson was how he finally made peace with his dad. He says: ''I had had it out with him, mano a mano. It was all right. He said, 'I know I treated you badly, I know I was firm with you'. We had a few drinks and we had it out. Which was very healthy. "
''That was the nemesis in my life; I carried it around with me, having to confront this upbringing. I am clear of it. It was cool. I can talk to him now on any level. I was a compulsive liar when I was a kid. Because everything at home wasn't right. Even as a kid, I was acting.''
But to expose it all on prime-time TV: what did his father think ? ''He was okay about it,'' he replies. He is sure that when his mum, Anne, began divorce proceedings, there was ''haemorrhaging and guilt'' that went on between his parents that was massive.
He says: ''Divorce was not a socially accepted thing in those days. And this was happening in a little mining village. The solicitor came to the house. Who is this guy with a 'tash and the old suitcase coming in ? My brother and two sisters and me, we were sent upstairs. Were they booking a holiday ? Then mum announced it. I understood. It was deeply upsetting, their arguments.''
Paradoxically, in Green's latest television project there is a very strong whiff of art imitating life. It is more than a touch masochistic to have just emerged from this much-publicised bust-up of his eight-year marriage to Allison Ogilvie, then having been scandalised by a couple of his affairs, and later he falls in love with Vanya - and to cap it all he promptly co-stars with Beth Goddard in Take Me, Scottish Television's new six-part thriller about a couple who attempt to salvage their failing marriage by joining the swinging couples set.
Freely admitting there are uncomfortably close parallels between himself and Jack Chambers, this venture capitalist son of a shipyard worker who returns to close the Newcastle yard which employs his father who beat him as a child, Green says: ''I am happy pushing the boundaries back.''
Chambers's father was a man of the people, a great union leader. Robson's dad, also called Robson, was a miner and union man who worked down the pits.
The role will surprise the legions of female fans used more used to seeing their idol playing the romantic charmer.
But he says: ''I have made these sweeping statements many times that I would never play a baddy. But a baddy you care about - now that is interesting.''
Such risk-taking has helped boost him to one of the highest-earning television actors.
Unfortunately, his colourful private life has masked his professional achievements for which he could be viewed as a role model for inner city kids who struggle to improve their position in life.
