In the near future, a portal to another universe opens up five miles beneath the surface of the Pacific, leading to the emergence of myriad monstrosities that relentlessly assault such chaos-magnet metropolises as Los Angeles and Tokyo. To counter the threat, the military develops high-tech mechas to battle the creatures.

The movie looks set to be a homage to the Japanese kaiju genre of movies, most famously exemplified by the Godzilla series. In an interview with Wired, del Toro described the movie as a “very beautiful poem to giant monsters,” as well as prominently featuring “25-story-high robots beating the crap out of 25-story-high monsters.” He also stated that the film would deal with the political and geological ramifications of the sudden appearance of such creatures.

Filming on Guillermo del Toro’s Pacific Rim has now been underway for over six weeks at Pinewood Toronto Studios, taking up five of the complex’s seven soundstages.

In an interview with io9, del Toro revealed that initial filming was for the Hong Kong-set complex where the mechas are maintained and will continue at the studio until April.

Pacific Rim will star Charlie Hunnam, Idris Elba, Rinko Kikuchi, and del Toro stalwart Ron Pearlman, and is set to begin its rampage through cinema screens on May 10th 2013.
