Maybe I can give some sense of scale to the amount of work that goes into something like this for those questioning it? :)

As you can see in my sig, I'm the mysterious "guy" who did the from-scratch CG on this project (who was amusingly referred to as a whole "team" it seems by MojoLA! :)) For just the small handful of shots for Ep IV Revsted I put work into, I spent about 500 man hours plus about 1500 rendering hours, work done on and off over ten months. Obviously, Ady did not do just a few shots of Episode IV but the entire freaking movie and all the sound and DVD work by himself too!... worked on it almost every day (and many hours of those days) for over two years! :O So, I can tell you for sure that my household put in about 2000 hours in, and it can surely be surmised that this number must be absolutely completely dwarfed by the time Ady put in, probably to an exponential degree! :O Just to back up what some others have said. :)
