Prime Video’s romantic comedy adaptation of Ali Hazelwood’s bestselling novel The Love Hypothesis drops on September 23, starring Lili Reinhart and Tom Bateman. The film’s unique genesis connects Bateman to his real-life wife, actress Daisy Ridley, whose appearance in the Star Wars sequel trilogy originally inspired Hazelwood’s viral 2018 “Reylo” fan fiction.
- Tom Bateman stars as Dr. Adam Carlsen in Prime Video’s adaptation of The Love Hypothesis, hitting screens on September 23.
- The original novel by Ali Hazelwood started as a Star Wars fan fiction on Archive of Our Own, drawing inspiration from characters portrayed by Daisy Ridley and Adam Driver.
- Bateman and Ridley, who married quietly before she confirmed the nuptials in 2023, were unaware of the fan fiction lore and casting connections until after Bateman joined the project.
Unraveling Hollywood Serendipity and the “Reylo” Pipeline
If you didn’t know better, you might believe the force that brought together Lili Reinhart and Tom Bateman, stars of Prime Video’s highly anticipated film The Love Hypothesis, was some stroke of long-game marketing genius. It started when an Italian neuroscience professor watched the Star Wars sequel trilogy running between 2015 and 2019 and fell in love with the dynamic between Kylo Ren and Rey, portrayed by Adam Driver and Daisy Ridley. Known to fans as “Reylo,” this passionate community inspired the professor to write “Head Over Feet” on Archive of Our Own in 2018 under the pen name Ali Hazelwood, which she later expanded into the bestselling romance novel The Love Hypothesis.
When Reinhart joined the project in 2024 on the set of the indie mystery-thriller American Sweatshop, she was initially hesitant about taking on a romantic comedy. But the Stanford PhD candidate Olive Smith and the brooding professor Dr. Adam Carlsen—named in homage to Driver—won her over. Reinhart didn’t even learn about the Reylo element until she had already acquired a copy of the book, noting that nobody told her right away. “And then they were like, ‘Oh, by the way, this does have a fanfiction attached to it,'” Reinhart shared.
Casting the Leading Man Amid Fanfare and Surprises
By 2025, Reinhart had come on board as a star and executive producer, granting her a direct hand in chemistry reads for the male lead. Finding the right actor to play opposite her proved daunting. As Reinhart explained, it is nerve-wracking to wonder what man wants to play second to a woman lead who is not an A-list star, wanting instead to surround herself with people who elevate her.
Tom Bateman, chosen for his acting chops, happened to be married to Daisy Ridley. In the film, Bateman plays a romantic counterpart to a character originally inspired by his own wife’s Star Wars role. Fans immediately took to TikTok and other social platforms to point out the poetic irony, though Bateman insisted to ScreenRant that he was only told about the inspiration after being offered the job. “They said, ‘By the way, this is loosely where the inspiration came from… but it wasn’t until the announcement of the cast that I became fully aware of how much love there is from the fans out there,'” Bateman told ScreenRant.
Reflecting on the internet’s skepticism, Reinhart laughed off claims that the couple orchestrated the casting. “If you knew both of them as I do—they did not know,” Reinhart said. Meanwhile, Ridley’s reaction to the casting was remarkably grounded. In an interview with Extra TV, Bateman recalled his wife’s response: “She just went, ‘I heard about that,’ but we didn’t think it was going to be a big thing… She basically said, ‘Anything that gets anyone reading.’”
Behind the Curtain of a Strictly Guarded Off-Screen Romance
The couple’s path to marriage is characterized by fierce privacy. Bateman and Ridley first met on the set of Murder on the Orient Express. Producer Judy Hofflund later recalled that a romantic connection formed during the film’s London premiere. Speculation regarding an engagement circulated in 2019, though Ridley guarded her personal life fiercely, telling Marie Claire at the time that she preferred to keep her relationships separate from public consumption. By January 2023, Ridley officially confirmed her marriage to Rolling Stone during an interview when asked about her ring.
The pair recently collaborated professionally on the 2024 noir thriller Magpie, which Bateman wrote based on an original idea by Ridley, who starred as the lead. “Being able to write to what I know her strengths are was so rewarding,” Bateman noted during the 2024 premiere. Despite sharing the screen and collaborating behind the scenes, the couple maintains a distinct boundary between their high-profile careers and their private lives, even as The Love Hypothesis pushes Bateman back into the center of a massive global fandom.
