HEROES bosses sparked upset by refusing to hire Irish actors to play Irishmen in the hit TV series - because they hated their accents. Actor Adrian Pasdar - who plays politician Nathan Petrelli in the sci-fi show - claims producers opted to hire Americans to play residents of County Cork because they preferred the sound of their voices, following a series of fruitless auditions with aspiring Irish screen stars. The 'Irish' actors were recruited for a scene where Nathan and his brother Peter - played by Milo Ventimiglia - end up in Cork. Pasdar says, "The irony is we had American guys playing the Irish guys in those episodes because the Irish actors who auditioned for the roles didn't sound Irish enough. "So the portrayal of the guys from Cork, I have to admit, was very interesting. So I don't know how much of it worked and how much of it didn't."
