Oliver Stone wants you to 'tu off your phone' - CNET

Controversial filmmaker Oliver Stone's latest project, "Snowden," takes a closer look at the life of an American people either view as a traitor or a hero for being an NSA whistleblower -- Edward Snowden.

In an unusual PSA called "Snowden - Oliver Stone 'Tu Off Your Phone" posted on YouTube Wednesday to promote the movie, the filmmaker reminds us that smartphones are a fun way to watch cute animal videos, but they can also be used to track our every move.

"The information you put out into the world voluntarily is enough to bu your life to the ground," Stone says in the dramatic video posted by Open Road Films. "This will be our undoing."

Even if Stone sounds slightly paranoid, he does suggest, with a bit more levity, that everyone watching "Snowden" inside a movie theater should tu off their phones. "Snowden," which stars Joseph Gordon-Levitt in the lead role, debuts in theaters worldwide in September.
