Some of the biggest movie franchises started as books
Youâve seen the movies. Maybe youâve even seen them five times. But did you know that Harry Potter, The Lord of the Rings, and The Hunger Games all began as books? Literary properties have powered some of the most profitable, long-running film franchises in history. These arenât just lucky adaptations-theyâre carefully built worlds that grew from pages into box office empires.
Not every book becomes a hit movie. In fact, most donât. But when the right story meets the right filmmakers, the result can be a franchise that lasts decades, spawns spin-offs, and turns unknown authors into household names. What makes these adaptations work? Itâs not just about fame or fanbases. Itâs about structure, tone, and how well the source material translates to screen.
Why some books turn into franchises-and others donât
Think of a book you love. Now imagine turning it into a movie. Easy? Probably not. Many novels are too dense, too internal, or too slow for film. A good adaptation doesnât copy the book word-for-word. It finds the heartbeat of the story and builds around it.
Take Harry Potter. J.K. Rowlingâs books are packed with magic, rules, and character growth. The films didnât try to include every spell or side character. Instead, they focused on the core trio, the rising threat of Voldemort, and the emotional journey from childhood to adulthood. That kept the story tight and cinematic.
Compare that to The Chronicles of Narnia. The first film did well, but sequels struggled. Why? The books are episodic-each one is a standalone adventure. Film studios tried to force them into a single narrative arc, which confused audiences. The source material didnât naturally lend itself to a serialized movie plan.
Successful literary franchises share three traits: a clear central conflict, strong character arcs, and a world that feels expandable. You can tell a single story from them, but you also want to come back for more.
How The Lord of the Rings became a cinematic landmark
The Lord of the Rings is the gold standard for literary adaptations. J.R.R. Tolkienâs books were considered "unfilmable" for decades. Too long. Too many characters. Too much mythology.
Then Peter Jackson came along. He didnât cut the story-he restructured it. He turned three books into three films, each with its own beginning, middle, and end. He gave each character a purpose, even the smallest ones. Gimli, Legolas, and Merry? They werenât just sidekicks. They had moments that changed the story.
The films also respected the tone. Tolkienâs world wasnât just fantasy-it was mythic. The music, the landscapes, the slow build of tension-all of it came from the bookâs spirit. The result? Three films that grossed over $2.9 billion worldwide and won 17 Oscars.
And it didnât stop there. The success led to The Hobbit trilogy, video games, TV shows, and a whole industry built around Middle-earth. The books were already popular. But the films made them global.
The Hunger Games: A modern YA phenomenon
When Suzanne Collinsâ The Hunger Games hit shelves in 2008, it was a fast-selling novel. But no one expected it to become a $3 billion film franchise. What made it work?
First, the setup was visual. A televised death match in a dystopian future? Thatâs easy to show on screen. Second, Katniss Everdeen was a relatable lead. She wasnât a chosen one-she was scared, angry, and doing what she had to survive. That made her feel real.
The films kept the bookâs political edge. They didnât dumb down the message about media manipulation and state control. That gave the series depth beyond action scenes. And because the books were a tight trilogy, the studio knew exactly how many films to make-and when to stop.
Unlike some franchises that drag on past their welcome, The Hunger Games ended cleanly. Thatâs rare. Most studios want to milk a cash cow. But here, the story had a natural finish. That respect for the source material helped keep fans loyal.
Game of Thrones: When a book series becomes a TV empire
While not a film franchise, Game of Thrones proves how powerful literary properties can be on screen. George R.R. Martinâs A Song of Ice and Fire books were sprawling, brutal, and full of morally gray characters. HBO didnât try to simplify them. They leaned into the complexity.
They cast actors who embodied the characters-not just looked like them. Peter Dinklage as Tyrion Lannister? He didnât just play the role. He became the role. The show didnât just adapt the books-it expanded them. New scenes, new subplots, new emotional beats that werenât in the text.
And it worked. The show drew over 30 million viewers per episode at its peak. It turned unknown actors into stars. It made fantasy mainstream again. Even after the show outpaced the books, it remained culturally dominant.
The lesson? You donât need to follow the book exactly. You need to understand its soul.
Why franchises like Twilight and Fifty Shades failed to last
Not every book-to-movie adaptation becomes a franchise. Twilight made $3.3 billion, but the films ended after five installments. Why? Because the story was built around one central romance, not an expanding world. Once Bella and Edwardâs story concluded, there was nowhere else to go.
Fifty Shades of Grey had a similar problem. It was a single, self-contained story dressed up as a trilogy. The sequels felt like stretched-out versions of the first book. No new stakes. No new characters. No growth. Audiences stopped caring after the second film.
These werenât bad adaptations. They just lacked the ingredients for longevity. A true franchise needs more than a hit. It needs room to grow. New locations. New enemies. New alliances. A world that keeps surprising you.
Whatâs next? The books still waiting for their moment
There are dozens of books right now that could be the next big franchise. The Stormlight Archive by Brandon Sanderson? A 10-book epic with magic systems, political intrigue, and gods walking among mortals. Perfect for a multi-film saga.
The Dark Tower by Stephen King? A mix of Western, fantasy, and horror. Itâs been tried before-and failed. But with the right team, it could finally work.
Even older works like Leviathan by Scott Westerfeld or The Name of the Wind by Patrick Rothfuss have passionate fanbases and rich worlds. Studios are watching. The question isnât if theyâll adapt them-itâs when.
What makes a literary franchise last?
Itâs not about how many books there are. Itâs about how well the story holds up when you take it off the page.
The best adaptations:
- Respect the tone and themes of the original
- Focus on characters audiences care about
- Leave room for expansion-new locations, new villains, new rules
- Donât rush the story. Let it breathe
- Know when to stop
Some franchises live forever because theyâre more than movies. Theyâre experiences. You donât just watch Harry Potter. You grow up with it. You rewatch it. You quote it. You imagine yourself in Hogsmeade.
Thatâs the real magic. Not the spells. Not the special effects. Itâs the connection.
Whatâs the next big literary adaptation?
Right now, the most talked-about upcoming adaptation is The Wheel of Time on Amazon Prime. Itâs based on Robert Jordanâs 14-book series. The first season stayed close to the books. The second expanded. The third? Itâs starting to feel like a real franchise.
Other possibilities:
- The Kingkiller Chronicle - A lyrical, character-driven fantasy with a narrator who may be unreliable
- His Dark Materials - Already adapted as a TV series, but a film trilogy could dive deeper into the multiverse
- The Broken Earth trilogy - A climate-fueled dystopia with powerful magic and emotional depth
These arenât just stories. Theyâre worlds waiting to be built. And if the right team takes them on, they could become the next generation of film franchises.
Why do some book adaptations fail while others become franchises?
Book adaptations fail when they try to copy the book too closely or ignore its core emotional arc. Successful franchises focus on characters, world-building, and themes that can expand beyond a single story. They leave room for sequels, spin-offs, and deeper exploration-not just more of the same plot.
Can any book become a movie franchise?
Not every book can. A franchise needs a strong central conflict, a world that can grow, and characters audiences want to follow over time. Episodic stories or those focused on a single emotional arc-like romance or personal trauma-usually donât have the depth for multiple films.
Whatâs the difference between a successful adaptation and a faithful one?
A faithful adaptation tries to match the book scene by scene. A successful one captures the spirit of the book-even if it changes details. The best film franchises, like Harry Potter or The Lord of the Rings, made smart cuts and added new moments to serve the screen, not the page.
Do book sales go up after a movie adaptation?
Yes, often dramatically. After the first Hunger Games film, the books sold over 20 million copies worldwide. Harry Potter books saw sales spikes of 500% after each movie release. The films act as giant billboards for the original books.
Why are fantasy and sci-fi books more likely to become franchises?
Fantasy and sci-fi books often build entire worlds with their own rules, cultures, and histories. That makes them easier to expand into sequels, prequels, and spin-offs. A story set in a single city or focused on one relationship doesnât offer the same growth potential.
What you can learn from these franchises
If youâre a writer, study how these stories were adapted. Notice what stayed. What changed. What was cut. The best adaptations donât just translate-they transform.
If youâre a fan, look beyond the movies. Go back to the books. Youâll find layers the films couldnât show. Deeper backstories. Hidden themes. Quiet moments that made the characters real.
And if youâre waiting for the next big adaptation? Keep reading. The next billion-dollar franchise might be sitting on your shelf right now-unnoticed, waiting for its moment on screen.
