Pacific Rim is a 2013 American science fiction monster film directed by Guillermo del Toro, and starring Charlie Hunnam, Idris Elba, Rinko Kikuchi, Charlie Day, Robert Kazinsky, Max Martini, and Ron Perlman. The screenplay is by Travis Beacham and del Toro, with a story by Beacham. The film is set in the 2020s, when Earth is at war with the Kaijus, colossal monsters which have emerged from an interdimensionalportal on the bottom of the Pacific Ocean. To combat the monsters, humanity unites to create the Jaegers: gigantic humanoid mecha, each controlled by at least two pilots, whose minds are joined by a neural bridge. Focusing on the war's later days, the story follows Raleigh Becket, a washed-up Jaeger pilot called out of retirement and teamed with rookie pilot Mako Mori as part of a last-ditch effort to defeat the Kaijus.
Del Toro envisioned Pacific Rim as an earnest, colorful adventure story, with an "incredibly airy and light feel", in contrast to the "super-brooding, super-dark, cynical summer movie". The director focused on "big, beautiful, sophisticated visuals" and action that would satisfy an adult audience, but has stated his "real hope" is to introduce the kaiju and mecha genres to a generation of children. While the film draws heavily on these genres, it avoids direct references to previous works. Del Toro intended to create something original but "madly in love" with its influences, instilled with "epic beauty" and "operatic grandeur". The end credits dedicate the film to Ray Harryhausen and Ishirō Honda, who helped to establish the giant monster genre with films such as The Beast from 20,000 Fathoms and Godzilla respectively.
The film was produced by Legendary Pictures and distributed by Warner Bros. It was released on July 12, 2013 including releases in 3-D andIMAX 3D. While the film received positive reviews, with the visual effects receiving particular praise, and was highly successful in many other territories, the film was a disappointment at the United States box office. It earned a worldwide total of more than $411 million, including $114 million in China, its largest market.
