My ONE problem...only one? For the moment, it will be portrayals of characters by actors who don't fit, which brings me to two that come right onto mind -
Ben Hur - the 1959 version, in which Judah Ben Hur, an ancient world Jew from Jerusalem, is portrayed by blond, northern Euro Charlton Heston, a guy who seems completely off and never even wears appropriate clothing.
And then, there's a corollary, which is how aristocratic Roman characters in Ben Hur, as well as many other movies, are generally played by guys with British accents, even when they're American actors and they have to mimic a British accent. For what it's worth, having studied Latin at a young point in my life....Latin sounds nothing like British English. Not even a bit. The worst there might be Jay Robinson, who did the emperor Caligula in a couple of movies, notably Demetrius and the Gladiator. Robinson spoke New York English, mimicked a British accent for the role, playing a Latin speaking Roman.
Got that off my chest.
