Oliver Stone Wants You To Turn Off Your Phone.

Ahead of his forthcoming thriller Snowdon Oliver Stone has appeared in a PSA advising cinema goers to turn off their phones so the NSA doesn't track them and also so they won't come across as nobs to their companions.

The video features Stone extolling the virtues of mobile devices before a quick tone shift has him indicting phones as surveillance devices of shadowy government agencies.

It's all very intense.

The Irish release date for Snowden has yet to be announced.
