Go Inside The Head Of The 'Pacific Rim' Jaegers

A new featurette from the set of "Pacific Rim," Guillermo del Toro's massive monster movie that is also this summer's best robot movie, takes us literally inside the heads of those battle machines to see how they brought the fights to life.

Del Toro wanted to the action inside the head of the enormous jaegers to feel authentic and that meant helping his actors deliver believable performances, despite the fantastical circumstances of the story. "Helping" may not be the best word to use, because what del Toro ended up doing was strapping his actors into heavy machinery that would force them to strain in order to move their limbs.

The results was a more convincing monster and robot fight, which pretty much speaks for itself.

"Pacific Rim" opens on July 12.
