The author of Forrest Gump the source for the titular movie, was contracted to earn 3% share of the profits. The film made about $678 million on the budget of $55 million, but Paramount did not pay Groom, using Hollywood accounting to posit that the film indeed lost money.
Winston Groom was paid $350,000 for the screenplay rights to his novel Forrest Gump and was contracted for a 3 percent share of the film’s net profits. However, Paramount and the film’s producers did not pay him, using Hollywood accounting to posit that the blockbuster film lost money. Tom Hanks, by contrast, contracted for a percent share of the film’s gross receipts instead of a salary, and he and director Zemeckis each received $40 million. Additionally, Groom was not mentioned once in any of the film’s six Oscar-winner speeches.
Groom’s dispute with Paramount was later effectively resolved after Groom declared he was satisfied with Paramount’s explanation of their accounting, this coinciding with Groom receiving a seven-figure contract with Paramount for film rights to another of his books, Gump & Co. This film was never made, remaining in development hell for at least a dozen years.
