I know a number of people who moved from across the pond that actually do American phonemes fairly well. What gives them away are minor inflections and sentence cadences that sound a little off. Hard to describe, but it makes them sound like the are trying to speak to everything “as a matter of fact” and towards the very front of their mouth. For an example, listen to Freddie Highmore in season 1 of Bates Motel.
