Holographic movies require a high bandwidth and a lot of storage space (recorded/pre-rendered). Current holographic displays require a movie-source for every few-point. And to make it convincing for a small POV (e.g. 19" 4:3 holographic monitor) you need at least 8 few-points, for a 360° next-gen holographic display you would many terrabytes of data for one movie (and a high bandwidth to stream the data to the display). Depending on the holographic technology you need additonally a very high resolution in contrast to the visual output. If you use a common HD resolution the current visible pixel range is about 640x480 - at least some expensive research displays I used in 2011.
