Jon: To be sort of a knucklehead kid from (Washington) D.C., and then to be able to tell my old man I was going to Harvard, it was a good thing for me!
Jon (About working with Oliver Stone): Just an honor. He's one of the greatest film makers this country's ever had. It was an honor to be a part of this movie. I think the movie managed to be really about the resolve of this city and this country. And there's nothing political about it. And it really memorializes and honors the day's heroes.
Jon (About 9/11): These guys, they saw this terrible inferno, this hell, and they decided to go back in, and they decided to go in. And it's something that should be celebrated. I'm really excited and pleased with the movie. And I think it does exactly that.
Jon (About his role in World Trade Center): I looked at (his role) as sort of a responsibility, or a duty to Chris and his family. You know, Chris was in the building that day. He saved a woman. He cut his ear, and then he was on his way out, where he saw his friends. And he made the decision, he insisted, to go back in.
Jon: "WTC" is about a team of five PAPD officers who head into the burning towers in an attempt to save lives, only to get buried under the rubble of the collapsing buildings.
Jon (About World Trade Center): Whatever good did come out of that day and how we as a nation came together, that's what the movie celebrates, and I don't think it's too early for that. I think it needs to be seen.
Jon (About World Trade Center): I don't think it's too early. I think we, as Americans, need to go see these guys' story. I think these people need to be celebrated. They need to be memorialized. And I think the movie really celebrates the resolve of this city.
