According to Black, his original first draft of the script was very different and much darker than the final film. It was 140 pages long and both the plot and characters were different, and action scenes were also much bigger. The ending of the script contained a chase scene with helicopters and a trailer truck full of cocaine exploding over Hollywood Hills with cocaine snowing over the Hollywood sign. Black hated this first draft and initially discarded it but later picked it up again and re-wrote it into the new drafts that were eventually used for filming.
