Snowden, 30, who disclosed details of the U.S. National
Security Agency's surveillance programs to news media last year,
has been granted asylum in Russia and risks being arrested and
extradited if he sets foot in any U.S.-allied country.
Greenwald was one of the first journalists to report on
Snowden's leaks in Britain's Guardian newspaper and won a
Pulitzer Prize along with documentarian Laura Poitras for their
work covering Snowden on the run.
Greenwald's book, "No Place to Hide: Edward Snowden, the NSA,
and the U.S. Surveillance State," came out on Tuesday and
explores his involvement and work with Snowden to report on the
NSA's intelligence-gathering activities.
The journalist said he was "very happy" to be working with Sony
Corp's Sony Pictures Entertainment to bring his book to the
screen, saying the studio has "a successful track record of
making thoughtful and nuanced true-life stories."
"Growing up, I was heavily influenced by political films, and am
excited about the opportunity to be part of a political film
that will resonate with today's moviegoers," he said in a
Michael G. Wilson and Barbara Broccoli from EON Productions, the
makers of the James Bond spy film franchise, will produce the
film. No announcements on casting, directing or release date
have been made.
