Jack Ellis is excited about the way Jim's character and story-line has developed this series: "We see Jim change and I hope that there is a little more humanity to him - although his behaviour is inexcusable you maybe see why certain things happen. We actually leave the prison walls and go to his home and meet his family, which really feels that it changes things for me as an actor - meeting 'the wife'".

"I do feel that I have now relaxed into the role, although my real-life wife has been heard to say on more than one occasion "can you leave Jim Fenner at work and just be Jack Ellis when you come home!"

For Jack playing Jim has been a real eye opener, "Jim is certainly a devious man but as with any character I've played I have grown to like him. His way of thinking is very un-PC, but it's something that I'm enjoying playing. He is the 'raw male' material and in a strange way it's quite a release".

"Jim's been in the service for 14 years and has the training and experience - something can kick off at any time and he'd deal with it. He's a good Prison Officer and demands a lot of respect from the women and from his fellow officers. People admire him when they see him operate. He fancies himself as a bit of a hero but feels that if you play everything by the book it doesn't work. His philosophy is that whatever action he does take, it's to his advantage - he will always get something out of it".

"Jim has a major problem with women. He's highly driven and sexually motivated and he doesn't think that badly about hitting a woman, which is unforgivable. By giving them a slap it will get them in to line again and that's what he does to Shell. That's what makes him think he's a good officer. His behaviour doesn't seem to send the prison into a spin. It seems to operate quite well, even though he is behaving badly and taking advantage. The prisoners seem to fall in line".

"I think that most of his fellow officers who work closely with him do have a good idea about his sexual relations with prisoners but turn a blind eye. He doesn't see he's doing anything wrong - it's there, they need it, he's providing them with something that they don't have on the inside …"
