There’s an excellent feature on John Williams over at The Wall Street Journal – do have a look:
Mr. Spielberg credits the composer for making him “a better director than I could have ever been without him.” Recalling the blockbuster that made them both household names, he describes the “esoteric” placeholder music he’d selected as a model for the “Jaws” score—and how Mr. Williams forced him to reconsider.
“He said, “Steven, it’s not an intellectual film. It’s a pirate movie,” the director says, adding, “John is like a great writer. He rewrites me musically every single time.”
After the success of “Jaws,” Mr. Spielberg nicknamed Mr. Williams “Max,” after Max Steiner, who wrote the first memorable original feature film score (for “King Kong”) and helped establish the orchestral language of the movies.
