Movie robots and monsters come in all shapes and sizes, from the very small to the impossibly large. But just how wide is that range? How gargantuan are giant big screen creatures compared to one another? Is Colossal Titan bigger than a kaiju from Pacific Rim? How does the Iron Giant stack up against Optimus Prime?  And where does the King of the Monsters, Godzilla, fit into all of this?

Stop arguing, because now you can see firsthand with these fantastic size comparison videos.
