CinemaBlend has an interesting look behind the scenes of the 3D retro-themed animated opening credits sequence in Oz The Great and Powerful. “Our opening sequence needed to set up this sensational 3D journey, up front, so that the audience kind of expects the whole entire film is going to be an adventure fantasy film. We purposely wanted to embrace every single trick in stereo, to make sure that the audience really enjoys the idea of this stereo journey”. Also included is some of the reference art the team used to get the old-timey feel.
