I have tremendous respect for fighters and I always tell people that boxing in movies is one thing but when you get into the ring for real, even the worst heavyweight in the world is going to murder you. You've just got to appreciate the pain and the suffering and the glory and skill that goes into what they do. That's why I love the sport so much.

Now it really is, believe it or not, 90% of the films are green lit, not by the studio heads, but by the marketing department.

That's what Rocky is all about: pride, reputation, and not being another bum in the neighborhood.

I want to turn my attention to movies about love relationships. Exploring the female psyche - there ought to be some interesting discoveries there. Love stories. If you do it right, people want to hear romantic dialog.

Rambo isn't violent. I see Rambo as a philanthropist.

The phenomenal thing that happened to me is that I was able to create two memorable men: one is the ultimate optimist, Rocky, and then you have Rambo, the ultimate pessimist. You're going to always be remembered for them, no matter what you do.

I used to tweet, but it's an act of futility. You're not really making any impact, and if you find yourself in a mood when you wanna be a bit controversial and you post something, you suddenly realise, 'Oh my God!' because you've opened yourself up to a bunch of criticism from strangers.
