Oliver Stone: Lit at Comic-Con

EXCLUSIVE

Oliver Stone ain't afraid to give you the cold hard truth ... when it comes to how he spent his downtime at Comic-Con.

The Oscar-winning director was in San Diego repping his new film, "Snowden," when he shot down a photog trying to ask questions ... in a totally friendly drunk kinda way.

You gotta hear Stone's excuse, which worked like a charm.
