 The character "Brock Hudson" was actually named after a real life  student of the same name at St. Johns School in Houston, Texas.  (The same school where "Rushmore" was filmed). The screenwriter Lee  Fleming went to this school, along with Wes Anderson (qv)  (director of "Rushmore" and "Bottle Rockets") and  Will Wallace (qv) ("The Thin Red Line" and "I am Sam") where the  phrase "what kind of name is Brock Hudson?" was commonly heard.
