And they did the VFX on a pretty tight budget! It just goes to show how going back to the days of careful planning and execution can lead to world class artistry without blowing up the budget and making people work 80-100 hour weeks for months on end. Unfortunately the way we do it now they don't plan shit carefully, constantly change the plan, rarely know what they want and would prefer to just make everyone work themselves into the ground. Sigh.
