Speaking to This Morning's Eamonn Holmes and Ruth Langsford, the actor said he was happy to return to the role after four years, but admitted an exciting storyline was key to getting him back to Corrie.He said: "They've always talked about Jim coming back and he is always mentioned, but I said: "I don't want to come back to have a phone call with Steve, the Street needs some men, get him back and do a storyline."."And sure enough this storyline came up and it was perfect, Peter Barlow ends up in the nick and he needs a bit of TLC in there and Jim is one of the daddies."It worked out terribly well."In the coming weeks viewers will see an alcoholic Peter rely on Jim to provide him with booze, but Jim also needs something from Peter...Charlie explained: "You do what you can inside to get by, so Jim has set up an illicit still, but he's also getting stuff brought in and he is keeping the prisoners happy as one of the daddies."And of course Peter arrives and Jim has no idea that he has a serious drink problem all he sees is a chance to do a bit of business, and the chance (to have ex-wife) Liz come and see him because he loves her."And he also wants to see (his son) Steve because he hasn't had a visit in four years, the poor wee man. So viewers will see all that develop, whereby some say it is callous, but I say he is just doing what he can to get by."And he uses Peter through Deirdre and Ken (Barlow) to get Liz to come and see him."So as Charlie's famous NI twang returns to the soap, fellow Northern Irishman Eamonn asked if he felt a sense of pride in representing his home on TV."By and large most people at home are desperately proud, as they are of you (Eamonn) and all the rest of us, (James) Nesbitt and (Jimmy) Ellis, God rest his soul."In the days when we started in the business, it was very grey and there wasn't that much good news, we had Alex Higgins and we had George Best, but an awful lot of the rest of it was grim."But now we have Rory McIlroy and Graeme McDowell!"Coronation Street airs on UTV every Monday, Wednesday and Friday from 7.30pm.
