Interesting twist, but even if somebody cant talk English fluently, they still know things. Especially if they are from Hungary. Yes, no, sorry, hello, I dont like, I dont understand, love, feel, haird dryer, etc... A lot of things have Eng;ish name in Hungary and everyday life you see them all around. If she is from Budapest than she must see them.
Eszter is acting dumb, not Hunarian. Her mom is played by a duthc/french woman, what is surrising. She can not tal Hungarian at all, and has dutch accent even for those few words.
USA is full of Hungarian people, a lot of them working in film industry too. Even Louis CK is 25% Hungarian, his grandfather was Hungarian.
Even the waiter is Russian. Learned a few sentences but clearly can not speak Hungarian at all. Very hard Russian accent he got.
It would be so much easier to get a Hungarian waiter and a Hungarian aunt to play the role.
"Ivanka" or what the hell is her aunt name and "amia"??? What is that? Never heard those names, not even Hungarian names.
Why not called Kata, or Eszter, Gabriella, or any normal common Hungarian name? Or even uncommon Hungarian name, like Szidonia, Mercedesz or Eszmeralda, but Amie and Ivanka or what the hell of therin names.. never been Hungaran name, nobody called like that in Hungary, and nobody have Russain accent if they not Russian.
