John Williams

Has anyone ever seen Steven Spielberg and John Williams in the same room together? They might be the same person, because these two work together a lot.

Williams has scored over two dozen Spielberg flicks, including Jaws, Schindler's List, all three good Indiana Jones films, and the other Indiana Jones. Williams also scored the first three Harry Potter films, so he knows how to create movie music magic.

Williams is known for his sweeping orchestral scores, and the iconic "Theme from Jurassic Park" is one of them, despite the unoriginal name. This stunning theme plays when the first dinosaur appears on camera. It creates a sense of majesty, which is hard to do when there's a brachiosaurus taking up the entire frame. But Williams's score stands up even to the largest of these lizards.
