Arh, Gowd bless yah, Murey Poppppins....!Much as I love him, I could never get over Sean Connery playing an Oirish cop with a very Scottish accent in 'The Untouchables'.... Kevin Costner again, but at least he wasn't trying to do the accent....
And Seans' Irish accent in 'Darby O'Gill' isn't that bad, after all, isn't the man half Irish himself, he being named after the doubting saint himself (his real first name is Thomas)? In fact, one critic mentioned his 'dark brown Irish voice' as far back as Dr No (1962) just 3 years after Darby.... (I really do need to get out more....)
