This dialog of film is inaccurate :

"But in 1953... The U.S. and Great Britain engineered a coup die-tat that deposed Mosaddegh... ...and installed Reza Pahlavi as shah."

The correct story is :

"...and installed Mohammad Reza Pahlavi as shah."

I wonder, what a shameful mistake the producer didn't paid attention.

Here is documentary from Wikipedia: The 1953 Iranian coup d'état (known in Iran as the 28 Mordad coup[3]) was the overthrow of the democratically elected government of Iran, and its head of government Prime Minister Mohammad Mosaddegh on 19 August 1953, orchestrated by the United Kingdom (under the name 'Operation Boot') and the United States (under the name TPAJAX Project).[4][5] The coup saw the transition of Mohammad-Rezā Shāh Pahlavi from a constitutional monarch to an authoritarian one who relied heavily on United States support to hold on to power until his own overthrow in February 1979.[6]
