Legendary announced the release date with this tweet earlier today :
— Legendary (@Legendary) April 24, 2015 The original Pacific Rim was released on July 12, 2013 and met with an astounding success raking in $411 million for the producers. The Pacific Rim story starts in 2013 when the human cities are attacked by the Kaijus, colossal beasts who come to Earth through a portal on the Pacific Ocean floor called the Breach. To combat them the Pacific Rim nations build the Jaegers, equally colossal robotic war machines. Each Jaeger is piloted by two or more pilots whose brains are linked (called “drifting”) to share the mental load of operating the machine. The Jaegers are initially effective, but many are destroyed as the Kaijus grow more powerful and their attacks more frequent. In 2025, the governments deem the Jaeger program ineffective and discontinue it in favor of building massive coastal walls. The four remaining Jaegers are redeployed to Hong Kong to defend the coast until the wall is completed. When the wall fails to stop the Kaijus, the only left fleet of two Jaegers, Gipsy Danger and Striker Eureka are sent by commander Stacker Pentecost to fight the rising Kaijus by putting a nuclear bomb in the portal. Gipsy Danger crippled and Striker Eureka too damaged to deliver the bomb. Once inside, Raleigh ejects Mako’s escape pod and sets the Jaeger to self-destruct. Mako and Raleigh who are piloting Striker Eureka manage to get it on the other side of the portal and explode the nuclear bomb thus destroying the invading aliens and the portal. Raleigh is able to jettison his escape pod and travel back before the portal collapses. Mako and Raleigh’s escape pods surface safely in the Pacific, and the duo embrace as rescue helicopters arrive. Forbes had noted that Pacific Rim was the rare English-language film in history to cross $400 million while barely crossing $100 million in United States.
