Academy Award winning director Oliver Stone is make a film about Edward Snowden, one of two high-profile movies in the works about the National Security Agency whistleblower.

Stone said he planned to adapt The Snowden Files: The Inside Story Of The World's Most Wanted Man, a book by Guardian journalist Luke Harding.

The Platoon director will have stiff competition however: Sony Pictures purchased the big-screen rights to Glenn Greenwald's No Place To Hide: Edward Snowden, The NSA And The US Surveillance State. The film is being produced by James Bond producers Barbara Broccoli and Michael G Wilson.

Stone has advocated for the former NSA contract systems analyst, who is living in Russia on a temporary grant of asylum after leaking massive amounts of agency documents to the media.

"To me, Snowden is a hero because he revealed secrets that we should all know, that the United States has repeatedly violated the Fourth Amendment," Stone said at the Karlovy Vary Film Festival in the Czech Republic.
