I totally agree with that. I am from the part of Essex that is stereotypically Essex and if you didn’t know you probably wouldn’t guess. I’m told often that I don’t sound like an Essex girl. But I like it, and challenging people’s preconceptions ; )
Same! I’m from one of the market towns in Suffolk and honestly, the amount of people who’ve lived here all their lives and have asked me where I’m from is astounding.
What’s odd about Adam to me is that he almost sounds like an American trying to put on an English accent, rather than an actual Englishman! Strange…
I do tend to find that that happens whenever I see an English actor on an American TV show, though—we’re so used to hearing the American accents that the sudden introduction of an English accent is so jarring that it sounds ‘wrong’ and exactly like what you said. Flip that, however—take something with an English cast, and a single American actor doing an English accent, and nine times out of ten you can tell.
