Based on: Forrest Gump by Winston Groom
Year published: 1986
Groom’s novel actually has quite a few key differences than the 1994 blockbuster film. Most noticeably the ending: (Spoiler alert!) Jenny does not die, but rather reunites with Forrest at the end.
In 1995, following the success of the movie, Groom wrote a sequel, Gump and Co.
