The marketing campaign for Guillermo del Toro’s great-looking new film Pacific Rim is about to be kicked into high gear, and as a result Warner Bros. has now released a nearly 4-minute behind-the-scenes featurette for the pic.  For those unaware, the story is kicked off by the emergence of monsters (known as Kaiju) who start a war that devastates humanity.  To fight back, humans build giant robots (known as Jaegers) that are controlled by two pilots.  This featurette gives a clear outline of the story and the world that del Toro and screenwriter Travis Beacham have created, and it also provides a nice behind-the-scenes look at del Toro’s process as a director and his approach to crafting the Pacific Rim universe.

Hit the jump to watch the featurette, and if you missed any of Steve’s set visit coverage, be sure to check out his video blog recap and 20 things to know, plus his interviews with Guillermo del Toro, Charlie Day, Ron Perlman, and executive producer Callum Greene.  The film also stars Charlie Hunnam, Rinko Kikuchi, Idris Elba, Clifton Collins Jr., Max Martini, and Rob Kazinsky.  Pacific Rim opens in 3D on July 12th.

Here’s the official synopsis for Pacific Rim:

When legions of monstrous creatures, known as Kaiju, started rising from the sea, a war began that would take millions of lives and consume humanity's resources for years on end. To combat the giant Kaiju, a special type of weapon was devised: massive robots, called Jaegers, which are controlled simultaneously by two pilots whose minds are locked in a neural bridge. But even the Jaegers are proving nearly defenseless in the face of the relentless Kaiju. On the verge of defeat, the forces defending mankind have no choice but to turn to two unlikely heroes—a washed up former pilot (Charlie Hunnam) and an untested trainee (Rinko Kikuchi)—who are teamed to drive a legendary but seemingly obsolete Jaeger from the past. Together, they stand as mankind's last hope against the mounting apocalypse.
