The US movies and television industry can rarely get any language right. This reminds me of the Dutch-speaking scene in Oppenheimer which no Dutch speaker can understand [1]. It's like a sped-up pronunciation of a nonsense Dutch sentence by an English-speaker trying to speak a horrible German accent.
To be fair, they do this with a lot of location in the US as well. "New York" is often Atlanta or Toronto in many American movies.
However a novice in a foreign language will speak more slowly than natives, not more quickly, even if reading a prepared speech (as was likely the case in that setting, and especially given the advanced language used that no beginner would have mastered), so not sure what the thinking was there.
I will admit that they nailed the German-Dutch accent.
However, the weird choice to use “translatie” which, while technically is a Dutch word, wasn’t common even back in the period this is supposed to take place and feels more like a lazy translation of… well the English word “translation”, combined with, what I can only describe as “just blurt it out as fast as you can” direction, makes this very comical.
