"Pacific Rim" officially started shooting in Toronto, Canada, on November 14, 2011, and ended in April 2012. The director himself mentioned the progress of the film to the media at the end of the second week of filming. During the filming process, the codename of the film was called "Silent Seas" and "Still Seas".
Before the film, Gilmore Del Toro had never finished filming a movie within 115 days, but the filming cycle of "Pacific Rim" was only 103 days. In order to achieve this goal, Del Toro drafted a separate unit so that he could start work every day earlier than the main unit, as well as make it on his rest days. During these 103 days, Gilmore Del Toro worked 17-18 hours a day, 7 days a week. In addition, he also adopted a new method to direct the performance of the actors. He allowed the actors to have "failure" actions and improvisations; however, the whole film was shot under the firm control of Del Toro. He said that all Things, 100% have to pass through him sooner or later. He controls everything. Some people like this, some people don't, but in order to complete the film, this is the only way.
"Pacific Rim" was shot with Red One digital camera from Red Digital Cinema Camera. At the beginning, Gilmore Del Toro did not intend to make the film into a 3D movie. He believed that the huge size of the mecha and monsters in the movie would not bring good effects to 3D. However, it was later announced that the film would provide a 3D version through conversion, and the conversion cycle exceeded 40 weeks. Gilmore del Toro cut the original footage about an hour from the film.
