I'm always amazed at how British actors, or really ANY actors are able to sound like an American in movies. Maybe it's not as hard as I think but I can't do it.
My wife has family from England and the kids are able to do this quite proficiently. They think that it's from watching American television and streaming services.
And probably if you try anything long enough, you'll get good at it. Our kids in turn have gotten pretty good at emulating their cousins across the pond.
Now we just need to figure out a way for them to make money doing this!
CAUTION: There are a few beeped out swear words.
