Diablo Cody
Brooke Busey-Maurio (born June 14, 1978), better known by the pen name Diablo Cody, is an American writer, director, and producer. She first became known for her candid memoir, "" (2005), and the blog that preceded it. Later, Cody achieved critical acclaim for her debut feature film script, "Juno" (2007), winning awards such as the Academy Award for Best Original Screenplay, the BAFTA Award for Best Original Screenplay, the Independent Spirit Award for Best First Screenplay, and the Writers Guild of America Award for Best Original Screenplay.
Dan Brown
Brown was listed as one of the executive producers of the film "The Da Vinci Code", and also created additional codes for the film. One of his songs, "Phiano", which Brown wrote and performed, was listed as part of the film's soundtrack. In the film, Brown and his wife can be seen in the background of one of the early book signing scenes. (Dan Brown looks briefly into the camera at time code 06:12 - 06:14, next to his wife, but both are a bit out of focus, so it's hard to catch when you watch the movie.)
