Great deal of this movie is not true. Yet, this movie tells about 1/100th of the truth about the tyrant of Baghdad and his family in the 1990's. The other 99 parts are still under oblivion, thanks the the author and to the current chaotic regime of Baghdad. The movie is fine because even that 1% counts to understand what was really going on for the people in Iraq at that time.
But there is a serious drawback when someone watches this movie knowing that at the time of movie release in 2011, the main character and the author, Latif Yahia, was (and still is) glorifying the tyrant and calling on people to re-establish his era in Iraq. He actually has a YouTube channel filled with his political opinions and his shameless strange sympathy to the tyrant!! So whatever the author's claims about his political views, or about his own opinions of not having political views; he was not opposing the tyrant, and still not; he was one of the tyrant's followers and still is.
Now watching the movie knowing that the writer and main character stands there, it will make the audience uncomfortable and cautious to accept what's being told in this movie without questioning.
Aside from that, directing was weak in general, and the story is not as the original Arabic book (I Was A Son For The President), but a revised version of the English edition which was a revised version of the Arabic edition!
For example in the Arabic edition the main character was claimed to be a ranked army officer, in the movie he was just a soldier. In the original story it was claimed that the tyrant saw and examined his son's double for a few times, in the movie that wasn't happening. Now if this was a history book/movie then.. voila! There is a good definition for the person who says what he doesn't think and thinks what he doesn't say, and changes his saying/thoughts 3 times in a day...
