All wideshots of the city devastated and destructed by terrible earthquake were digitally extended. Many 3d mattepainting shots are full CG. Plus actually the earthquake itself of course. As the film is really based on a trues story and many survivors of the actual disaster are still alive and came to the theaters the critical goal for us was to reconstruct the city and action extremely accurately from the old pictures and video chronicles. Yet the time for post production was stressing – just 2 months. Check the result in a short reel.
