Looking over this thread, I noticed it is mostly contemporary times British actors/actresses but how about one from 84 years ago, Vivien Leigh who played the character Scarlett O'Hara in the classic movie, "Gone with the Wind" (1939)

Other non-Americans on that cast:

Leslie Howard as Ashley Wilkes (born in London in 1893);

Olivia de Havilland as Melanie Hamilton (born in the Kingdom of Japan to British parents in 1916);

Ann Rutherford as Careen O'Hara (born in Vancouver, British Columbia in 1917);

Victor Jory as Jonas Wilkerson (born in Dawson City, Yukon, Canada in 1902);

Joseph M. Kerrigan as Johnny Gallagher (born in Dublin, Ireland in 1884);

and

Lillian Kemble-Cooper as Bonnie's nurse (born in London in 1892).

Still haven't seen that movie yet; what did you think of it?

I've talked about quite a few non-Americans in the MCU but can't believe I haven't talked about Tom Hiddleston yet.

Born Thomas William Hiddleston in London, England, he of course has been on Disney+ playing the title character of Loki for two seasons and on 3 episodes of What If...? as the beloved villain, as well as across the MCU:

Thor (2011)
The Avengers (2012)
Thor: The Dark World (2013)
Thor: Ragnarok (2017)
Avengers: Infinity War (2018)
Avengers: Endgame (2019)
Ant-Man and the Wasp: Quantumania (2023)

Still can't believe he was ever in the running to play Thor - Aussie Chris Hemsworth has so embodied the role that I can't see anyone else doing it now.

Here he is not only speaking in his native English accent but also doing his excellent impressions of Al Pacino and Robert deNiro from Heat - in front of deNiro himself.

It was okay as an action movie.  Quite a long runtime but the time went quick.  I thought the story-line is weakish. Overall I enjoyed it.

Star Trek "A Space Adventure Hour" Season 3 episode 4. 

Christina Chong who plays La'An Noonien-Sing in the show, put on an American accent for some of the episode.

Jess Bush who play Nurse Christine Chapel is Australian.

I remember that at the original Star Trek, there were no longer separate nations on Earth, it was just a combined planet.

He is also in the new Fantastic Four movie.

Vanessa Kirby and Joseph Quinn are also British.

How about Dan Aykroyd or Leslie Nielsen? Canadians can pass off as American real easy.

William Shatnet is Canadian.

Off the top of my head other Canadians:
Keanu Reeves -Donald Sutherland and Kiefer Sutherland

But I bet there are lots more.
