War is always seductive, ... 'Full Metal Jacket' didn't make me want to join the Marines. I already had fallen in love with the idea of combat. I think whether somebody feels that about our movie is subjective. It depends on the viewer. I got letters from people who said 'I was thinking about joining up and I read your book and now I can't wait' and I got letters from people who said 'I was thinking about joining up and I read your book and now I'm going to go to college.'
I never saw it as a political book, ... I wanted to open up a world that people might not know anything about. It's up to the people who go to this movie to decide how they feel about it, just like it's their job as Americans to decide how they feel about the war. We're asking the viewer to take responsibility for how they feel.
