As HatiHot says, the language is not right. And the categorisation is a mish-mash - fancy putting it in a category "Arab." Spanish and Persians would both have a case against that. However, the guy in the film is at least acting like an Iranian. He has shaved his pubic hair, and, despite his wife having a fleshy, attractive, vulva, he has ignored it and gone in the back door, instead.
