Spielberg has desire to work with Zhang Yimou

Spielberg positioned cameras during filming of Jurassic Park to take advantage of depth of field, meaning there were a lot of animals coming from the background and quickly coming into the foreground.

"It was 3-D technique without the use of actual 3-D. I have done that in Jurassic Park more than in my other films. That's why it would be an easier conversion to bring it out in 3-D."

He said there are no plans to convert The Lost World: Jurassic Park or Jurassic Park 3, although he is working on the script for Jurassic Park 4, which will be filmed in 3-D format. There are also no plans to reach back into his library of films to convert them into 3-D.

"Someday I may change my mind, but right now I cannot think of any film that I want to convert into 3-D except for Jurassic Park."

He said 3-D technology is more like a choice or tool and not necessarily a staple for filmmaking.

"3-D is a choice that studios and the filmmakers can make if they feel they can give the audience an enhanced experience by shooting it or converting it into 3-D," he said.

"I would not be interested in making a love story in 3-D, or a personal small drama in 3-D because I have a strong philosophical belief that 3-D is not for every movie, but for certain types of pictures."
