Are there any American actors or characters in foreign films?

So, we see tons of Brits and British characters in British films these days. It's kinda unusual for me if at least 1 character (or actor on a popular series) isn't played by a British actor. It makes sense as it's perfectly normal for someone from London or Sheffield to move to the US (if it's the character). Or simply British actors can easily get roles in Hollywood.

But it got me wondering, are there any Australian or British or French or Indian films that feature American characters or American actors/actresses on them?
