Behind the scenes: Oz the Great and Powerful By January 2012, edits of live-action footage began reaching Sony Pictures Imageworks. Simultaneously, work began on some of the film’s more complex digital environments. It was an evolving process, and part of this creative evolution was in terms of the film’s 3D demands. Scott Willman, the film’s stereography supervisor, came on board immediately after the principal photography was complete, for which the on-set 3D stereographers had been Ed Marsh and James Goldman. One of Wilman’s key responsibilities was to oversee how animated characters would tie in with the movie’s 3D aesthetic. Willman recalls that Raimi’s feedback upon reviewing the 3D footage was to “make it bigger”.
