I've been watching The Serpent (no spoilers please!!) on Netflix and I'm wondering why they cast actors who can't speak a language in these parts. I get Jenna Coleman looks the part but surely they could have found an actress in the whole of Quebec who would have done. The same for the Dutch guy, why cast someone who can't actually speak Dutch?
I don't speak Spanish, but the guy they cast as Fring in Breaking Bad could not speak Spanish at all. He sounded awful. Or does it just not matter? Perhaps it doesn't bother people.
I know some actors can do accents better than others but has any actor actually managed to fake speaking a language they don't actually speak well in a TV show or movie?
