Benedict, who portrays Julian, had apparently reached out to infamous whistleblower before filming to request a meeting. The WikiLeaks founder declined and responded with a long letter explaining why he refused to meet with the actor, while voicing his concerns over the film.
In the letter, Julian calls the film "wretched" and says the script was based on “toxic” books about his organization.
"I believe you are a good person, but I do not believe that this film is a good film," he wrote.
“Your skills play into the hands of people who are out to remove me and WikiLeaks from the world … I believe that you should reconsider your involvement in this enterprise,” he added.
WikiLeaks had previously posted the script from the project and described it as "fiction masquerading as fact,” blasting the film for its inaccuracies.
The Fifth Estate made its world premiere at the Toronto International Film Festival last month to a standing ovation, though it’s received a very low score (41 per cent) on the movie review website Rotten Tomatoes. It's slated for release on Oct. 18.
