Look, if you're dealing with giant monsters, furthermore, giant robots...shit's going to get wrecked. So, when you think about Guillermo del Toro's Pacific Rim and the on-screen carnage, you think B-I-G. After all, it's about the human race creating giant robots to contend with the giant monsters that threaten the planet.
In an interview with Total Film, Del Toro was asked about the scale of which his film is dealing with, the maniac responded with this: "When we’re talking about the physicality of the fight, we ended up building several blocks of Hong Kong. And literally demolished them. We built a building and then we took down the buildings. We built command centres of the robots that were the size of the house. We started them on hydraulic rigs that shoot and elevated them and moved them round so you could really get a sense of the physical nature driving a robot like this."
