Alfred Hitchcock, after seeing "Jaws," said that young Steven Spielberg "is the first one of us who doesn't see the proscenium arch." By which to say that free of the theatrical conventions that informed every other filmmaker before him, Spielberg was the first truly modern director. Since then, he has emerged as a Hollywood force unlike any other, one of the first filmmakers since Hitchcock whose name has become a brand, and whose films have made $9.1 billion worldwide.
