Ben Price and Jack P. Shepherd are not afraid to be "quite nasty to each other" on ‘Coronation Street’ because they are so close in real life.
The 47-year-old star – who plays Nick Tilsley in the ITV soap – admits it is vital to "go for it" when the brothers are at war on the cobbles, and that is made easier because he finds it "very easy to work with" Jack (David Platt).
When asked what it is like playing squabbling siblings, Ben said: "Yeah, we love all that. We do get on really well and because of that we are not afraid to be quite nasty to each other.
"It’s essential when you are going for it, you go for it.
"It’s very easy to work with Jack because we both recognise that, especially on ‘Coronation Street’, you have to show different sides of a character.
"This is a family story and that’s why I think they are such a strong family because we all play our parts."
Nick will appear in court next week, alongside David, after he stole their gran Audrey Roberts’ (Sue Nicholls) £80,000 inheritance money, and David helped him spend it when they bought barbers Trim Up North.
But Nick looks set to resort to desperate measures to try to ensure he stays out of prison.
Ben said: "There’s a duplicity with Nick. He’s now thinking that actually he better come clean but I don’t think he would have been that altruistic if he hadn’t have been caught and if it hadn’t have all came out.
"Initially he thinks he probably should take the blame because a lot of it was down to him but Nick is also very aware about what he is trying to create and when it all starts to fall down and he thinks he can’t get his way out of it, he realises he is going to have to show remorse in some way so part of that is using David to show the family that he has got remorse.
"He is very torn. Suddenly it becomes real that he might go away for a long time and the life that he is trying so hard to build up again could go.
"He starts to think if he keeps quiet there is a chance he could get away with it.
"His brother has been inside and done all that so he thinks that David won’t mind so much."
And he will blame his brain injury – which occurred in 2013 when David caused him to crash the van they were travelling in, which left Nick in a coma for nearly two months – on what happened.
He said: "It is a fact, he does have a brain injury. I don’t think that really made him do the things he did but he has been different since so he thinks he can have a legitimate go at using that as an excuse."
