Vulture has posted their interview with Nicolas Winding Refn. When asked about Keanu and whether he saw John Wick, he said the following:
Yes, I did — and I loved it. My favorite line in many years is, [Refn does Keanu Reeves impression] “Everyone keeps asking if I’m back. And you know what, yeah, I think I’m back!” It’s like, “Do you feel lucky, punk?” One of the great action lines. I really like Keanu. The thing about him which is so unique is that he’s the only movie star I can think of that actually transcends generations. Every ten years, a new generation rediscovers him in their own way. I don’t know anyone else who has done that.
