Oliver Stone thinks this near failure was due to self-censorship by major film studios. It only takes a few adverse consequences to infect many people and agencies with the mechanism of self-censorship. Obviously with Edward Snowden considered as an official enemy of the US state, any film that portrayed him in a positive light would be considered not in the national interest (read this as ruling capitalist class interest). This makes me wonder how many films are not made or not distributed because of self-censorship.
The film is scheduled to be released on September 16th.
