The American Accents are way off sometimes...

[SNAFUGuy]

Anyone else notice that the American accents are way off sometimes? In season 8 with Genevieve O'Reilly is the most glaring. For the most part she does a good job at the accent, but when her character get's angry she slips into a Aussie accent. I wonder if only other American viewers catch on to when the actors do this? I watch a couple of other UK shows and I notice that quite a few UK actors flub on the accent, especially if it's a American regional accent. Why not just hire Americans for the job? I know that a few of the American actors in Spooks were actual Americans but even then sometimes the vernacular is off, sentence structure what not. It doesn't bother me it just really draws me out of the moment when it happens.
