The Cast of 'Pacific Rim' on Working with Guillermo del Toro's Giant Aliens

Idris Elba, Charlie Hunnam, Ron Perlman, Charlie Day and Rinko Kikuchi share what it was like working with the creations from Guillermo del Toro. "I got an extensive sort of education on who we were fighting and what it would look like and loads and loads of some of the early images and even models to show you who was who," says Idris. "When we get to shoot it and have to image it, we had a good understanding of what it was like."
