Some of the best sci-fi movies of all time came from beloved novels. And, more often than not, the movies make some sweeping changes to the source material to function as they need to on the big screen. But, to that point, the level of changes vary from project to project. For instance, Blade Runner captures the atmosphere of Philip K. Dick’s Do Androids Dream of Electric Sheep?, the plot is altered to be more action focused. Steven Spielberg’s Ready Player One kept the characters and love for nostalgia but changed up the challenges and built up the character of Art3mis.
Jurassic Park is another notable example of a movie that kept the bones of the book but significantly altered the tone and characters (the book even kills off its extra unlikable John Hammond). But these following examples? They adhered to the text and were all the better for it, including the fantastic Project Hail Mary.
5) Project Hail Mary

Genuine commercial and critical smash Project Hail Mary is likely going to be considered as 2026’s definitive crowd pleaser when we hit December. It also does a marvelous job of capturing the experience of reading Andy Weir’s novel.
Not much is changed here. Ryland Grace is played very well by Ryan Gosling, and his relationship with Rocky is just as effective on screen as it was in the book. Some supporting characters have their roles cut short, and Rylan’s tumultuous dynamic with Eva Stratt is made more pleasant in the movie, but overall from first scene to last it’s straight out of the book.
4) The Hunger Games Franchise

The Hunger Games kicked off a franchise that is going strong to this day. The question is, will the upcoming The Hunger Games: Sunrise on the Reaping be as faithful to Suzanne Collins’ books as the remainder of the franchise? Because, for the most part, they’ve adhered very well to the text.
The books’ big moments and character arcs are all present throughout the movies. The only sacrifices that are made are necessary ones. After all, these wouldn’t quite work as three or three and a half hour movies. At the very least the box office would have been gutted. The movie version of The Hunger Games: The Ballad of Songbirds and Snakes also makes young President Snow a little bit more palatable, since he’s the movie’s protagonist. As for the Katniss era, there is a change not entirely unlike the one made for the Harry Potter movies. Specifically, as they went on, they were relegated to Harry’s POV. In The Hunger Games, we get a bit of a reversal of that. The book plays out from Katniss’ POV, whereas the movies show some events unfolding that are outside her POV.
3) The Martian

An absolute blast for fans of scientifically accurate movies and astronaut movies in general, The Martian is a must-see for any Project Hail Mary fan. This is not only because it’s basically a one-man space show but also because both of them come from the mind of Andy Weir.
Not only is the Ridley Scott movie fairly faithful to science, but to Weir’s book, as well. Mark Watney, the protagonist, remains the same individual, the tone holds steady, and the plot’s developments are as integral to the film as the text.
2) Dune (2021)

The first third of what will almost certainly be viewed as one of the best overall book adaptations of all time, even 20 years from now, Denis Villeneuve’s Dune is something special. It pulled off the unenviable task of successfully adapting Frank Herbert’s novel, which was once thought unadaptable. Not even David Lynch could accomplish that.
Both Dune and Dune Part Two are faithful to Herbert’s first novel in the series. The pace is tightened up, and Chani and Alia’s roles in Part Two are altered a bit, but that was for the better. In the book, Chani is consistently loyal and believing in Paul, while in the movie she has a more realistic reaction to his being granted so much power. As for Alia (Paul’s sister), she’s not even born in the movie. Instead, it’s Paul who kills Baron Harkonnen.
1) Arrival

The most visually and thematically stunning sci-fi film of the 2010s, Arrival is a modern masterpiece of its genre. It’s also the one entry on this list that is based on a short story, not a novel.
Because of that, some might find this one to be a cheat, but hear us out. It expands upon the short story, of course, because it had to. But in terms of capturing the tone of Ted Chiang’s “Story of Your Life” it is right on the money. The additions mostly come in the form of the military presence, but as for the whole linguist interacting with an alien angle and the communication’s side effect of allowing her to see the past, present, and future simultaneously (the real core of the movie), that’s all there on the page.
