The charming children's book was closely adapted by Disney for its 1961 film. Smith also wrote a sequel to the book, The Starlight Barking, in 1967 — which Disney did not base any of its subsequent sequels on.

Year published: 1949

Based on: Terms of Endearment by Larry McMurtry
Year published: 1975

Based on: Shrek! by William Steig
Year published: 1990

The novel is actually the fourth book in the Chinese author's five-part Crane-Iron Series.

8. Forrest Gump
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.

Crowe also adapted the book into the screenplay.
10. The Graduate
Based on: The Graduate by Charles Webb
Year published: 1963
Webb wrote the novel — his first — during his final year of college, and while both the movie and the book are essentially the same, this is one of the rare cases where the film is actually better.
In 2007, Webb wrote a sequel, Home School, that gave us the answers to what happens to Ben, Elaine, and of course, Mrs. Robinson.
11. Apollo 13
Based on: Lost Moon: The Perilous Voyage of Apollo 13 by Jim Lovell and Jeffrey Kluger

14. Rambo: First Blood
Based on: First Blood by David Morrell

15. Die Hard
Based on: Nothing Lasts Forever by Roderick Thorp
Year published: 1979
Thorp wrote the book as a sequel to his 1966 book The Detective, which itself had been adapted into a movie of the same name, starring Frank Sinatra, in 1968.
Nothing Lasts Forever was adapted into screenplay for Sinatra to star in — as sequel for The Detective — but after he declined, the script was rewritten as a standalone film.

Year published: 1963
The classic sci-fi novel was first published in France in 1963 and was translated into English the same year. Like the film, the book has it's own twist ending.
Boulle's other well-known novel, The Bridge Over the River Kwai, was also made into a classic film.
19. Blade Runner
Based on: Do Androids Dream of Electric Sheep? by Philip K. Dick
Year published: 1968
The film was loosely based on the book — in fact the term "blade runner" does not even appear in the book.
Other popular films based on Dick's writing include Total Recall, A Scanner Darkly, Minority Report, and Paycheck.
20. Field of Dreams
Based on: Shoeless Joe by W. P. Kinsella.
Year published: 1982
This classic guy-cry film was originally going to be titled Shoeless Joe — like the novel — but the name was changed after filming completed, due to executives at Universal hating the name.
Ironically, Kinsella's original title for the book was The Dream Field, but his publisher hated it and made him change it to Shoeless Joe.
21. Ordinary People
Based on: Ordinary People by Judith Guest
Year published: 1976
Guest's now classic debut novel was actually turned down twice before it was published. One publisher said in the rejection letter, "While the book has some satiric bite, overall the level of writing does not sustain interest and we will have to decline it."
Obviously they were wrong: The novel caught the interest of Robert Redford, who liked it so much he bought the film rights for his directorial debut. The movie went on to win four Academy Awards, including Best Picture and Best Director.
Based on: The Sheep-Pig by Dick King-Smith
Year published: 1983

25. Who Framed Roger Rabbit?
Based on: Who Censored Roger Rabbit? by Gary K. Wolf
Year published: 1981
The book is actually quite different than the film; two of the major differences include the setting — it's set in the world of comic strips, not cartoons — and Eddie Valiant is actually trying to solve Roger's murder, who we also find out had murdered someone himself.
