In several quick scenes of Tehran city,there is a very tall tower that believe must be Tehran International Tower which has been built within 2003-2007, long after revolution.
In a part of the movie, movie posters are shown that men take from the wall. These types of posters were definitely collected long before the time of the movie story. After the revolution, some films were made without women wearing the full hijab, but not with the low amount of coverage seen in the posters.
Throughout the movie, actors are shown saying "yalla" as a Persian for come on. However, yalla is an Egyptian Arabic for come on, let's go or let's do it which has also got popularity in Israel as a loan word.
When Isaac is put against a concrete wall to be shot (but purposely missed just to scare him), the bullet holes in the wall around him are clearly made by explosive squibs inside the wall, not by bullets hitting it from the outside.
The license plates of none of the cars shown in the movie match the shape of the license plates used in Iran in the time of the movie's story.

When Amin and his family are escaping from the guards, on the wall of some buildings, a more modern examples of split air conditioners can be seen, which were not available in Iran at the time.
The glasses that Salma Hayek's character wears are a style popular around the time of shooting, not the actual time of the story.
The few moments of Farsi speaking do not match the movie scenes; For example, when they take Amin to the place of execution to scare him, they tell him to get up when he is standing and walking, and it is also completely recognizable that all the Persian parts were spoken by one person.
