I’m amazed by how some actors/actresses can keep a credible “foreign” accent during a performance.Every time I try to mimic a British accent I sound like an Aussie.
No sure what that means.
That said, Robert Downey Jr did a fine job in his Sherlock Holmes performances.
A little stiff perhaps, but still fine.
My attempts at any British Isles accent slides into a terrible southern mixed with Indian accent. It is truly awful or maybe comical? Our youngest has a speech impediment, one of the issues is corrupted vowels. Some of her vowels sound rather British; my older kids blame all the British mysteries I watch. They say she absorbed it while in the womb and as an infant.
Something I find funny is when there is a terrible American accent in British TV shows. I once watched a theatrical version of an Agatha Christy Tommy and Tuppence mystery and the American character looked like Colonel Sanders and sounded like someone trying to imitate him but failing badly. They can no longer make fun of Americans trying to speak with a British accent.
So does the Geico Gecko...
I have a pretty healthy Southern accent. When visiting in Ireland, everyone asked if we were Australian.
