The Hollywood actress plays upper class English lady Elise in the new movie, opposite Johnny Depp as an American holidaymaker.
And the Oscar-winner reveals she studied etiquette and learned to move with poise to make her portrayal accurate.
She tells America's Today show, "I'm not completely clumsy or gross, but there's something about this type of woman that didn't come naturally to me. She takes her time with everything. I'm an American! I do 10 things before breakfast."
And when host Matt Lauer asked whether she took "manners classes" in preparation for the role, Jolie replied, "In a fashion, yes.
"There wasn't somebody you could call and say, 'Come over and give me a class.' But in a fashion, there was a way of studying certain things, reading about certain things. But it all added up to the same thing, which is, 'She needs to speak more elegantly. She needs to sit with more poise.'"
