From presidents to serial killers, Oscar-winning filmmaker Oliver Stone hasn't shied away from exploring controversial figures, but he initially balked when asked to make a film about former National Security Agency (NSA) contractor Edward Snowden.
Stone told Reuters, "I didn't want to do it, I wasn't looking for trouble."
But the 70-year-old director, known for films such as "JFK," "Natural Born Killers" and "Wall Street," said he changed his mind after he met with Snowden in Russia.
