Has anyone ever noticed/called out the movie industry on it's ridiculous notion that if a movie is set in a time period waaaaaay back in the day, the characters should have a British accent?

-300, takes place in Sparta...not Britain.
-Gladiator, takes place in Rome...not Britain.
-Troy
-Alexander.
-EVEN PHANTOM OF THE OPERA. FRANCE, NOT BRITAIN.

There are more examples that I can't think of, but it's ridiculous.
