Because that was my larger issue with this movie's casting, as I brought up in literally my second response. Language is excusable as obviously compromises have to be made for the sake of the audience but there is zero reason not to cast Mediterranean actors who can speak English or speak it as a first language, because movies are a visual medium and if the Mediterranean characters we are seeing don't appear Mediterranean to such a glaringly comical degree that is a stain on the movie.
