Sometimes, when a role in a film or TV show requires a character to speak in a certain language, and there are no suitable actors available that are fluent in it, one takes the actors available and have them learn their lines by rote. This creates a unusual situation where the actors who do this do not truly understand what their own characters are saying. Can sound very grating to viewers who are fluent in the language the actor is attempting to speak, as they are guaranteed to mispronounce and have problems with intonation. It's either this or As Long as It Sounds Foreign.
