Say what you will about this entry, (I know I’m no huge fan of his) but his creation of Star Wars completely changed Nerdom. Not only were special effects pushed to the limit like never before, but merchandising the property alone had a huge impact. Nerdom became mainstream in a way like never before. With Star Wars, Lucas presented something old and borrowed in a new light. Toys based on science fiction properties were not new, but with Star Wars, they exploded and continue being made (and remade) to this day. Just the first Star Wars movie could have been enough to earn Lucas a spot here, but for better or worse, he produced more in the Star Wars series and also gave Nerdom another valued contribution in Indiana Jones.
