He made Terminator and Titanic among others.
The 14 years includes developing the story and waiting for the technology to actually make the film the way he wanted to. Also, I don't think Cameron was involved with Jurassic Park....Spielberg made that movie.
My bad. I'm not so good on action movies.
I saw an interview that Sigourney Weaver did that said Cameron INVENTED and has the patent on the new cgi and 3D programs they used in the film...
She said it took 8 years of filming alone..
The fact that it took so long and he built the tech himself says a lot about him as a director and an artist. I'm glad people don't churn stuff out standard 3d offerings, like the far too many kids films that have been coming from most big film companies.
Disney turned animation into an art...I'm not convinced that 3d has found it's art form yet, except for the Shrek films.
Back on the topic of CGI, for me it still hasn't reached the standard of good-old "special effects" with the real humans being cult in. A lot of what has been coming out the past ten years has looked overly smooth or pixely or just plain fake. One of the reasons I hate Die Another Day is the flakey CGI used in it, and flakey CGI to me makes like the film company cut corners and do things on the cheap. The ice did NOT look real. The key advantage of film as a medium is that it can have in theory unlimited or a huge number of pixels, of which are indistinguishable by the human eye; the key disadvantage of computer generation is that unless one is doing vectors, there is a limitation on dimensions and complexity of the project, in part caused by the processing power of computers of the day.
I'm far from sold on CGI, but it Avatar has nailed it or got closer.
