Red Rock's lead writer has said that they may have to subtitle the show for American audiences.
The hit TV3 show will now be going Stateside after being snapped up by Amazon in a four-year deal reportedly worth €1m.
Writer Kim Revill said she won't be surprised if they are asked to provide subtitles, given that some of the actors have strong Irish accents - particularly the Dublin family, the Kielys.
"It's great that they can watch us in America. Now I want to go back and change some bits, but I have wondered if we'll need subtitles for them?" she said.
"There are some characters that I think they will struggle with. I think some of the phrasing with the Kielys could be hard."
The acclaimed writer, who previously worked on BBC hit soaps like EastEnders and Holby City, said that she loves writing for an Irish audience.
"I live here now and I love writing here. There's a certain turn of phrase and rhythm of speech here and I love writing it. I've been writing Cockneys on EastEnders for several years, so this is a real treat."
The programme has been going down a storm with Irish audiences, even though it has only been running for less than a year.
It beat off some stiff competition to pick up three Ifta's last October, and Kim said that she's been bowled over by the reaction to the soap.
"The Ifta's were amazing, especially to get the People's Choice. The whole thing was like being on another planet," Kim added.
The past few weeks has seen the programme gradually building up the tension as focus turns to the blackmail plot between the unfortunate Paudge and Beady Burke.
Things will take a decidedly dark turn on December 30, when viewers will see one of the lead characters meeting a brutal death in a major Christmas cliffhanger.
The show airs twice a week - on Wednesday and Thursday - but TV3 plans to extend the number of weekly episodes as it continues gaining a foothold in the ratings battle.
Representing a significant multi-million euro investment on the part of TV3, they began making the show after losing the rights of Coronation Street and Emmerdale to UTV Ireland last year.
TV3 owns 50pc of the show, with the rest of the rights split between the production companies Element Pictures and Angel Station.
