Brosnan and Mirren have been critiqued for their accents in the show, however Brosnan is under the spotlight since he is originally from Drogheda, Co Louth. Even though he was born in Ireland, fans consider his performance in MobLand unconvincing.
The actor defends his role and the TV show as he states in an interview with Radio Times that "My own accent is very soft" and that he worked with a dialect coach to prepare for this role, he continues “I told him that I needed a Kerry accent,’ he said. ‘So he gave me the name of a man and I Googled the guy and that was it. It was a Kerry accent. And so, I just gave it full tilt.”
The Irish actor also explains that he was initially worried about taking on the role and that Guy Ritchie was encouraging him to go "more irish" whilst filming. Brosnan says "Literally on the day, five weeks later, I was with Guy and he said, ‘Go more Irish. More Irish."
Brosnan explains in his interview with Radio Times the anxiety he feels before taking on a new role, "Every job is a challenge and it all comes with a thump of anxiety, because you have to do something. What are you doing on the stage? Why are you there? So that’s constant. You live with that,” he said. “You live with that stress all the time, and that’s what’s so exhilarating. That’s what makes you alive."
Mirren, who plays his co star in the film has jumped to his defence as she says "Brilliantly, I have to say. A pig farmer who’s actually spent a lot of time in London. There is a bit of London in there, too. There is a big community in London of Irish people and a lot of very specific Irish pubs and Irish traditions in London."
