The cast of "Pacific Rim" slipped out of their robot armor and into well-tailored suits for the movie's premiere on July 4.
Charlie Day ("Horrible Bosses"), Idris Elba ("Thor"), and Charlie Hunnam ("Children of Men") cleaned up and stepped out for the event in London, along with the movie's director, Guillermo Del Toro ("The Hobbit").
In "Pacific Rim," Hunnam, whom most people will recognize from the TV series "Sons of Anarchy," takes the lead as a washed up pilot of a group of robots called Jaegers, which were created to combat a species of monstrous aliens that have invaded Earth. Elba plays a military leader, while Day plays a scientist behind the robots' creation.
