Arjay Smith: (On the set of "Day after Tomorrow") We did have a few scenes in front of the blue screens. They actually had a set and inside this studio – I mean this studio was just unbelievable. They had like New York streets built with cars, flooding with water to the top. We did a lot of stuff in the studio. We only did a couple of days outside in the actual snow. It was –40 when we were out there, so our stunt doubles really had to do the hard stuff outside. Everything was done inside and a lot of the scenes take place in this library.
