Film producer Peter Jackson has recently admitted he often has to hold back when working on computer-generated imagery.
Jackson, who has been working on Steven Spielberg's The Adventures of Tintin: The Secret of the Unicorn, recently explained he often had to make sure he was not getting carried away when working on certain scenes.
During an interview with Superhero Hype, Jackson said: "You can go back to get angles you didn't think of on the day."
The director discussed both the advantages and disadvantages of working with computer-generated imagery, explaining that a CGI shoot allowed more freedom.
"You try to treat it as a real movie, to keep from going crazy with difficult shots, but sometimes you can't help yourself," he said. "You have to know when to stop."
When asked about the financial pros and cons of a CGI shoot he explained: "On a live-action set you have hundreds of people working and if it clouds over or rains, which it does from time to time in New Zealand, they're just sitting there waiting for it to stop and it's costing hundreds of thousands of dollars."
The producer finished by saying that both types of films were equally as expensive as each other, since CGI often needed extensive time for both pre- and post-production.
The Adventures of Tintin: The Secret of the Unicorn will be released October 26, 2011.
