20 Actor Nationalities You've Been Getting Wrong All Your Life

20. Martin Sheen

"Martin Sheen - well, he's the guy who went down the river to hack Marlon Brando to death with a machete in Apocalypse Now, and didn't he play the PRESIDENT of the United States in The West Wing? Well, gosh, you can't get much more American than that." Well, You Sort Of Can... Martin Sheen is an American, that's true, but he's not probably quite as American as you originally thought, given that his real name is... Ramón Antonio Gerardo Estévez! Oh, yes, here we go. So he was born in Ohio, sure, but his father was Spanish, and his mother was Irish. Which explains Ramón Antonio Gerardo Estévez, we guess. Or, at least, to some extent.

19. Cary Grant

"That transatlantic accent marked this actor's heritage as something of a mystery, but he spent the sum of his career in Hollywood movies, playing Americans, surrounded by other Americans, being all American-y. It would be wrong to assume that he was actually from somewhere else. Right?" Wrong! Cary Grant was actually English and was born in Bristol. His real name was (brace yourself) Archibald Leach, which is... nice? He was made an American Citizen in 1942.
