I’m not a linguist, so I’ve never had anything to back it up, but the Latin spoken by actors in movies always was a pet peeve of mine. Heavily American accented, like a high school dropout from Staten Island reading some random text for the first time. That, and medieval peasants with shiny rows of perfect, brilliant white teeth. And Nazis speaking English amongst themselves with fake German accents. And people who use the word “amongst”. In nomine Patris et Filii et Spiritus Sancti (Wikipedia approved version). Amen (ay-men, ah-men?).
