Academy Award-winning director Oliver Stone joined The O'Reilly Factor to discuss his new film about fugitive NSA whistleblower Edward Snowden.

Bill O'Reilly kicked off the interview by asking the director of JFK, Nixon and W. if he believed the USA was a "noble country."

"Yes, in its intentions," Stone replied. "I admire its history, much of it -- and I grew up here."

Stone admitted he leans left but said that as a filmmaker he tries not to let his personal political beliefs steer his films.

"I stay away from the politics. I really try to stick to my role as a dramatist. ... I'm not trying to lead you. I'm trying to lay out a story that happened from 2004 to 2013."

Stone said that Edward Snowden was discouraged with President Obama not keeping his promise of transparency.

"[Obama] doubled down on the Bush Administration's surveillance and other forms of warfare that they created."

O'Reilly then asked if Stone believed it was possible that President Obama and President Bush understood more about national security than Snowden did.

"No, I believe governments lie," Stone answered. "I think that they protect their own interests to get re-elected."
