Guillermo del Toro’s Pacific Rim is shaping up to be the blockbuster of the summer…

Warner Bros. and Legendary Pictures has released the first full-length trailer for the 48-year-old Mexican director’s monster movie.

The trailer expands on footage that was unveiled at WorldCon last month.

Pacific Rim centers on an alien attack that threatens the Earth’s existence, and the giant robots piloted by humans that the government deploys to fight off the invasion.

It stars Charlie Hunnam, Idris Elba, Charlie Day and Clifton Collins Jr.

Pacific Rim opens nationwide on July 12.
