I live near Comber in Co.Down and have friends who went to RBAI, Andrew's school - called Inst, btw. Titanic is on tv at the moment and Andrew's accent is annoyingly and completely wrong. It is not remotely like a middle class and educated Co.Down accent.Well...were the both Scottish? I suppose somebody who knows accents could see where Murdoch was from and where Ewan Stewart is from and but two and two together.
In other news, whenever I watch ANTR I am confused why the guy playing Thomas Andrews sounds so British. Wouldn't he have has a more Victor Garber in "Titanic" accent?
