Zero Dark Thirty - Alterations Because of the CIA
Whenever Hollywood needs the help of the US military or important information from agencies for a movie, the topic of censorship is something that has to be dealt with. Insider info, access to expensive equipment or the possibility to shoot at original locations has its price. Quid pro quo.
Of course, Zero Dark Thirty was affected by that as well since it shows very accurately how the hunt and killing of Osama Bin Laden went down. In order for screenwriter Mark Boal to be able to speak with a Navy Seal (among others), some passages had to be removed from the original script because the CIA said they were false. However, Boal didn't just want to get scenes approved but also get the confirmation whether they were accurate or not.
This led to the removal of a scene at the beginning of the script in which Maya (Jessica Chastain) actively takes part in the torture of a suspect. The CIA said that this wasn't correct. Also, another torture scene in which a prisoner is threatened by an aggressive dog was scrapped. The CIA declared that they did not use this method even though it wasn't forbidden by the US military (Washington Post). Furthermore, not only scenes with torturing were removed but also a scene in Islamabad where a drunken officer shoots with his AK47 in the air for fun.
