Filmmaker Oliver Stone, who is well-known for taking contrarian stands both onscreen and off, has criticised "Putin`s aggression in Ukraine" after previously saying there was "no proof" Russia intended to invade.

Stone went to Russia and interviewed its president for a documentary called `The Putin Interviews`, which aired on Showtime in 2017. Now, with Putin and Russia driving the 24-hour news cycle, the director has been offering his perspective on his Facebook page and in interviews, reports deadline.com.
