No jews in this??

Started watching this and immediately noticed all the actors playing the yeshiva bochurim were goyim (gentiles) it was extremely distracting although they did their best and the hair and costumes were prefect it was obvious bc they were too tall and looked very goyishe like midwestern farm boys! But Also the most distracting thing...they didn't talk like jews. Jews especially yiddish speakers have a unique cadence in speaking while some of the actors tried it really feel flat. Which is a shame because the movie is cute, and well written and really portays the ultra orthodox in a surprisingly positive light
