OK, here’s the rule regarding accents for films with international casts. As an example, we’ll use “The Fourth Protocol,” a 1987 movie starring Michael Caine as a British spy going up against the Soviets, because it grossly violates this rule. First option: Have actual Soviets play all the Soviet characters. Second option: Have all the Soviet characters speak with Soviet accents. Third option: Have all the Soviet characters speak with British accents (unavailable here since we also have British characters). NEVER ACCEPTABLE: Let Ned Beatty and Alan North play guys named Petrovic and Govershin but sound like they’re from Kansas.
