Hollywood completely screwed over the writer of the Forrest Gump book. This is how they did it.
The deal Groom made with Paramount was that he would attain $350,000 for the rights to his book as well as 3% of the film's total box office gross.
Seems fair, right? Unfortunately, the producers and movie studio did not end up paying Groom anything!
The reason for this was with a technique called "Hollywood accounting" which conned Groom out of his money by saying that the film lost money!
It was said that both Tom Hanks and director Robert Zemeckis earned $40 million from percentages in box office receipts!
Because of this incident, Groom refused to allow Hollywood to turn Forrest Gump's sequel, Gump and Co., Into a movie.
