I have chosen clips from from two actors that, could be considered representatives of their respective countries: Hugh Grant and Arnold Schwarzenegger.
That's my impression, what's yours?
This is the English clip.
And the American.
Well said.
Pure British films and tele tends to favor a much different lighting and filming style than the American counterpart as too. I don't know how to explain it without rambling but I think anyone who watches a lot of both would know what I am kinda talking about. There is a distinctive visual difference much of the time.
