Dubbing is hard. You have to translate text, rewrite it to fit cultural sensitivities, make sure it appeals to the audience and avoid changing the context.

Dubbing is even harder when you don't have a translator ready to understand the original language.

Fortunately, there's a common way to get around this: Base your dub on the language of another dub. It gets around the issue of cultural issues if it's from a similar country, and most of the translation work is already done.
