Rose: You're crazy. Jack: That's what everybody says but, with all due respect, Miss, I'm not the one hanging off the back of a ship here. Come on. C'mon, give me your hand. You don't want to do this.

There are many talented people who haven't fulfilled their dreams because they over thought it, or they were too cautious, and were unwilling to make the leap of faith.

I'm a curious guy. I can't turn away from an investigative story, when it comes to the forensic analysis. I've done 33 dives, to the titanic wreck site. I've spent over 50 hours piloting robotic vehicles at that wreck trying to piece together what happened during the disaster. How the ship broke up, comparing the historical record with the forensic record. Documentaries are kind of my new life. I love documentary filmmaking.

It's really the sense of isolation, more than anything, realizing how tiny you are down in this big vast black unknown and unexplored place.

The literature now is so opaque to the average person that you couldn't take a science-fiction short story that's published now and turn it into a movie. There'd be way too much ground work you'd have to lay. It's OK to have detail and density, but if you rely on being a lifelong science-fiction fan to understand what the story is about, then it's not going to translate to a broader audience.

I think "Avatar" is kind of a unique category where people are enjoying the unique theatrical experience even though they may have seen it on the small screen. They want to have that immersive, transportive experience. "2001: A Space Odyssey" played for three years at the Loews cinema in Toronto. I remember that. It just kept playing. People wanted to return to that experience. That may not be the best example because I think "2001" took 25 years to break even.

I love short trips to New York; to me it is the finest three-day town on earth.
