Guillermo del Toro's Pacific Rim had a presentation at this year's WonderCon, and the response was overwhelmingly positive.  They showed off plenty of new footage in a new trailer for the upcoming giant-monsters-vs-giant-robots flick, and now that trailer has landed online.  As Charlie Day's character says, it's "2,500 tons of awesome."  The new trailer provides a lot more info on the story, but it's the visuals that will really blow people away.  I felt bad watching it on my computer monitor because this is a movie that clearly demands to be seen in theaters.

Hit the jump to check out the trailer.  The film also stars Charlie Hunnam, Rinko Kikuchi, Clifton Collins Jr., Idris Elba, and Ron Perlman.  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.
