David Koepp - the master saboteur

From IMDB trivia: "Writer David Koepp said that when he was writing the script to this movie, he taped a fan letter next to his computer screen. The letter was from a viewer of Jurassic Park (1993) who complained he "waited too long" to show the dinosaurs in that movie".

Hah, talk about shooting yourself in the leg being motivated by a dumb fan letter.
