Not buying Emily Blunt's American Accent

Lol my bad. She had a great American accent in Dan In Real Life, there's a perfect example.

"That thing you're sucking on is not a Pina Coloda....."

Actually it was British.. She has a English accent, but for Prada she changed it up a little and made it British. They are so similar that it is hard for us americans to tell the difference. lol If I hadn't heard Emily in an interview talking about it - I would not have known either.

There is no general "American" elocution. The accent copied most often by most actors of non-specific, English, North-American parts is a straight mid-western without unusual inflection, but it is hardly definitively "American."

American includes a very specific Maine-towner, Long Island, all the boroughs of New York (heavens, Bronx is different from Brooklyn, which differs greatly from Queens, and all predicated on social class within the microcosms), three distinct Tennessee accents, North and West Virginia (hillbillies versus townies, of course), the two separate Carolinas, Georgia, separated very much by class, Chicago, the rest of Illinois (though upstate and downstate will tell you they can tell the difference), and all sorts of others, also separated by class, socialization, education and means. Unlike the stereotypical British, we have no single, definable "posh" accent (though the Brits will inform you that this single "posh" accent is also a fabrication), but the American inflection is no less complex, no less varied.

Standard Midwest is the general inflection to which most actors who are not attempting to portray a regional specific aspire, but it is hardly a definitive, nor even a singular, "American" accent.

Now, there is a general American language, as opposed to the Queen's English, per se, but this has nothing whatsoever to do with inflection, and everything to do with differing idioms and colloquialisms.

And Emily did not fail at developing *any* "American" accent; she obviously simply did not achieve the specific affectation some people expected - her accent in the film was entirely tolerable as one of the many, varied accents in the States.
