Knives Out (2019): Toni Collette mistakenly uses her natural Australian pronunciation of “simultaneously”. She then decides to go with it because she thinks the character is just that pretentious.

In Anglo-Australian English, simultaneously is pronounced with a short i-sound. Though she’s playing an American as Joni, Toni Collette mistakenly used her natural Australian accent to pronounce that word in one of her lines. She then decides she wants to leave it in because Joni would absolutely be the type to take a trip to the UK or Australia and pretentiously adopt foreign pronunciations for no reason.
