Whether it’s One Direction who inspired the author, everyone’s favorite vampireEdward Cullenor even characters from a galaxy far, far away, these five authors found major mainstream success — and some of them, even box office hits — in the stories they’d originally dreamed up as part of a fandom.

While this X-rated series is now better known as a trilogy of blockbuster movies that grossed more than $1.3 billion worldwide (courtesy ofJamie DornanandDakota Johnson’s on-the-nail portrayal of the protagonists),Fifty Shades of Greybegan as many other steamy romances did: fan fiction.
E. L. Jamesreimagined the relationship between the gorgeous and mysterious vampire, Edward Cullen, and the shy, love-struck object of his attention, Bella Swan. But in this version, Edward became a top-of-his-game businessman and Bella a young college graduate eager to make her mark on the world.
The author originally published the story on Fanfiction.net under the titleMasters of the Universein 2009,Forbesreported, before she self-published it as a novel in 2011 with a new title — and all the explicitTwilightreferences removed. With that, Anastasia Steele and Christian Grey were born.

“I spent a good hour or so Googling and trying to figure out who this kid was and in doing so I discovered that he often dated older women, and so the seed was planted,” she continued.

In 2020, the novel had a resurgence amidst the pandemic, and Lee spoke toVogueabout her intentions with the story, which she said, “was never supposed to be a book about Harry Styles.”
The inspiration for the love interest, Hayes, turned out to be a mix of elements: ex-boyfriends, her husband and a sprinkle ofEddie Redmayne. “I made him into my dream guy," she said. “LikePrince Harrymeets Harry [Styles].”
The story begins with a meet-cute that will feel familiar to fanfic readers: Soléne catches the boyband member’s attention while bringing her daughter to a meet-and-greet before their concert in Las Vegas, and Hayes is so smitten right off the bat that he invites the girls backstage after the show. From there, he can’t control his pursuit of her (despite their nearly two decade age difference).
Lee’s novelwill soon hit the big screenas it’s been adapted into a filmstarring Anne Hathaway as Soléne and Nicholas Galitzine as Hayes.

The most recent example of a fan fiction success story comes from Ali Hazelwood, whose first book,The Love Hypothesis, not only secured her spot as aNew York Timesbestselling author. It also marked the entrance ofStar Warsinto the traditionally published fan fiction canon.
In 2020, an agent contacted Hazelwood about a story she’d published on Archive of Our Own about Kylo Ren (Adam Driver) and Rey Skywalker (Daisy Ridley) — characters introduced in 2015’sStar Wars: The Force Awakens, perVulture. She reworked the story to flesh it out further, but kept the general plot the same.
The Love Hypothesisstayed true to its origins in many ways, and even features fan art on its cover.

Simon & Schuster
E.L. James is not the only author who found inspiration inTwilightand went on to carve out a successful book series because of it — author duo Christina Lauren, a joint pen name for authors Christina Hobbs and Lauren Billings, traveled a similar path.
Hobbs originally published the fan fiction storyThe Officeonline, where it garnered millions of views and became an instant hit in the vampire fandom, before she met and developed a friendship-turned-partnership with Billings. The pair rewrote the story to submit to traditional publishers.
She toldForbesshe had Billings “dissect” and “do whatever she wanted” to the original story as the pair was facing pressure to act as publishers were looking at modifying fan fiction for publication. The book was sold to Simon & Schuster and came out in its current form in 2013.
