Paul Ferris has admitted almost breaking down on the set of a movie about his life.
He filled up watching CID put a gun to the head of Martin Compston in The Wee Man.
Compston was filming a scene showing police raiding old man Thompson's house in Rothesay.
Paul told us: "I was watching this scene with great interest.
"I knew it was going to be pretty dramatic because the cops were obviously going to kick in the door and come looking for me - with all guns blazing.
"But then the woman playing my then girlfriend AnnMarie started screaming as they held the gun to Martin's head.
"The cops immediately backed down as they did not know she was there.
"I have learned to put moments like that way back to the back of my mind.
"But it brought it all back to me with a vengeance. It shook me up for the rest of that day.
"I would have been a goner if it was not for Ann Marie being there. It was hard to get my head around that fact.
"I now have kids and a wife and I love them dearly. All of that could have been taken away from me."
The film stills also show him as a Cat A con in the seg unit.
"That was also hard to deal with. I was thrown inside solitary like some kind of animal. What kind of society does that to another human?
"I hope when people see the movie they will understand why I am trying to set up a rehabilitation programme for offenders.
"This kind of punishment just fuels the anger and the resentment. Another of these film stills show Martin fighting with a prison guard.
"That is what you do when you have no other way to vent your frustrations. We need education and support to break the cycle of violence."
The stills are just a taster of what is to come in the movie released in August 2012.
It will also show the brutal deaths of Joe Hanlon and Bobby Glover whose bodies were dumped in a car on the day Arthur "Fat Boy"Thompson was laid to rest.
Fatboy, who told anyone who would listen he was killing six men on his first home leave, died outside his house with a curry in his hand.
In 1992, Paul stood trial for months but was cleared and given a hereos welcome on the steps of the Glasgow High Court.
Tam McGraw, played by John Hannah, and Thompson Snr, played by Patrick Bergin, are in the movie.
Paul said: "My friends Bobby and Joe were murdered and yet their deaths have never been solved.While it is painful for me and their families itshould never be forgotten.
"But their deaths are in no way glorified in this film.It is only one part of this story.
"It also highlights the rank police corruption within Strathclyde Police. It was not the whole force but there were many who were rotten to the core. I think that is why they refused to let the movie be filmed in Glasgow.
"Graeme Pearson used to be an assistant chief constable of Strathclyde Police and he has also been a major critic of this film.
"He is now a politician. You would think he would be interested to listen to what I have to say on this matter."
The movie opens showing a young Ferris being bullied by members of the Banks family . . .but we all know who they really are, and they ain't actually from Wales.
Ferris paid tribute to young Compston, director Ray Burdis and producer Mike Loveday for bringing The Ferris Conspiracy to the pictures.
He said: "Martin is a fantastic actor. There was no influence from me in any of this. He just went out and researched his stuff -and what he has done is brilliant.
"He is a true professional.
"Ray is an absolute genius. He and Mike Loveday have produced a fantastic piece of work. It is very clever."
The actors and production team worked 12 hour days over sixweeks. Filming finished earlier this month.
Ray was behind the camera on the Krays movie and knows his gangsters.
He said: "I amvery pleased with this film and I think it is on a par with The Krays. People should definitely go and see it.
"There is a lot of violence - yes - but it basically tells the story of a young boy who was bullied mercilessly and then kickedback.
"I know that some people have voiced concerns that the deaths of Bobby Glover and Joe Hanlon have been included but I assure them this has been done with the utmost sensitivity."
Ray said: "Paul came down to the set in London one day and some of the secondary actors did not know who he was.
"One of them was kind of acting a bit cocky so we just left him to it.
"You should have seen his face when he realised this guy was Paul Ferris - his jaw hit the ground."
