Found this on /. today about the technical requirements to make the visual effects. They used about 100 TB of storage for the film since it was shot primarily with IMAX cameras. Then the had to downsample the resolution from 18k (the IMAX resolution) to 8K (the maximum resolution the current film scanners support) so they could actually work with the footage. In comparison the author worked on Pitch Black, which was released in 2000, and that took up only 2 TB of data. A single frame of TDK took up 200 MB of storage, and that's at a fraction of what it could have been.
Amazing article for the geeks among us.
