Ali Hazelwood’s bestselling STEM romance The Love Hypothesis is officially making the jump to the screen, marking a major moment for readers who’ve been waiting for Hollywood to embrace Hazelwood’s brand of smart, nerdy love stories. The film arrives September 23, 2026, exclusively on Prime Video, positioning it as one of the year’s most anticipated book‑to‑screen releases.
At the center of the adaptation is Lili Reinhart, who not only stars as PhD candidate Olive Smith but also serves as an executive producer—giving her a direct hand in shaping the tone and emotional core of the story. Opposite her is Tom Bateman as the famously intimidating professor Adam Carlsen, a casting choice that immediately set the internet buzzing.
Plot & Themes
The story follows Olive, a brilliant but overworked scientist whose attempt to convince her best friend she’s “moved on” spirals into a fake‑dating arrangement with Adam. What begins as a strategic kiss quickly becomes a relationship governed by rules, boundaries, and a mutual agreement—until those boundaries blur and Olive is forced to confront the possibility that her “hypothesis” about love might be wrong.
The adaptation leans into the book’s signature blend of academic pressure, emotional vulnerability, and slow‑burn chemistry. Expect the film to highlight the tension between scientific logic and messy human feelings—one of Hazelwood’s trademarks.
