If I were to make a movie about a foreign land, culture, history, etc. I would do a bit of investigation first. The least I would do is to check my story with a native. Not one of the actors or actresses is from Iran or Iranian decent. And there are many of them available these days. The movie seems to be made out of the book by Soraya herself which does not necessarily match the historical events. For example, in Iran they did not have Emperors, they had Kings. King's palace called SADABAD is in north of Tehran and nowhere near the sea. This is a movie made for the taste of western audience and bent in a few places to make it more attractive to them. As a result, it has lost its exotic and factual touch.
