My duties were to assemble .exr files for nuke and Ae. Framestore and Dneg provided me their assets. Then Design holographic advertisements (similar to the ones in the film) and then insert (sandwich) them in-between the original composited layers. This was mostly for international cross-promotions for the films release. This is one of the most visually arresting films you have ever seen, with an unprecedented production scale. Dune will be just as beautiful.
