The term 'Wonder Boys', a derivative of the German 'wunderkind', refers to someone who has greatly succeeded in their profession or art at an early age. In the movie, Grady applies the term "Wonder Boy" to James specifically. During the DVD extras, director Curtis Hanson also applies it to Grady, though not in an entirely flattering way, since in Grady's case, the term refers to his early literary promise on which he has failed to deliver. In Michael Chabon's novel "Wonder Boys" (upon which this movie is based), the term also doubles as the title of Grady's giant unfinished manuscript, and "Wonder" is the last name of the brothers who are the main characters in that book.
