The whistleblower website posted a memo calling the movie "irresponsible, counterproductive and harmful." The film, due out Oct. 18, chronicles the birth of WikiLeaks with Benedict Cumberbatch playing site founder Julian Assange (ah-SAHNJ').
Assange has previously called "The Fifth Estate" ''the anti-WikiLeaks movie." In a lengthy, point-by-point posting, WikiLeaks refuted the film's depiction of WikiLeaks, disputing everything from its suggestion that WikiLeaks-published documents put confidential sources in danger, to the idea that Assange dyes his hair.
The filmmakers and Cumberbatch reached out to Assange in the making of the film, but were rebuffed.
Representatives with the film didn't immediately comment Sunday.
