Lili Reinhart & Tom Bateman Explore Unexpected Love Theory on Prime

Lili Reinhart and Tom Bateman bring the hit BookTok novel *The Love Hypothesis* to the screen in a brand‑new rom‑com that drops on Prime Video at 3 a.m. ET today, September 23.

The film follows Olive Smith, a PhD candidate who impulsively kisses her intimidating professor to prove she’s over a past crush. What starts as a stunt quickly turns into a faux relationship with rules, blurring the line between pretense and reality.

The story tests Olive’s bold hypothesis: that love may be worth the risk. She must navigate boundaries, friendship drama, and unexpected chemistry as she and Adam Carlsen, played by Bateman, question whether what began as a test could become something real.

Fans of the novel can now see their favorite characters in action just hours after the midnight release.

Prime Video is the sole home for the film, so viewers need a subscription to watch. If you’re new to the service, you can start a 30‑day free trial that includes Prime perks like free two‑day shipping and exclusive deals. After the trial, a standard Prime membership costs $14.99 .

## Background & Context

Ali Hazelwood’s 2021 novel *The Love Hypothesis* gained notoriety on BookTok for its quirky premise and was originally written as Star Wars fanfiction before evolving into a full‑length romance. The story’s popularity prompted the adaptation, making it one of the most‑anticipated releases on streaming services this fall.

The film captures the novel’s blend of humor, science‑fiction nods, and heartfelt moments that resonated with young adult readers worldwide.

The production team opted for a modest budget that focuses on character chemistry rather than lavish effects. Filming took place in studio sets designed to mimic a university research environment, reflecting the academic backdrop central to the plot.

This approach keeps the narrative grounded and lets the performances shine without the distraction of high‑budget spectacle.

## Plot & Characters

Olive Smith is a driven PhD student who finds herself in an awkward moment with her professor, Adam Carlsen, after a night of tension. To impress her best friend and signal she’s over her former crush, Olive impulsively kisses Adam on the campus quad.

Their ensuing agreement—an elaborate “fake relationship” with rules and boundaries—provides comedic fodder as well as emotional depth.

The film also features a supporting cast that adds layers to the story: Rachel Marsh portrays Anh, Jaboukie Young‑White takes on Malcolm, Nicholas Duvernay plays Jeremy, and Arty Froushan appears as Tom. Each character contributes to the academic and romantic subplots, giving the film a well‑rounded ensemble feel.

The central tension revolves around whether Olive’s hypothesis—that love can be risked for genuine connection—holds true. As the lines between pretense and affection blur, viewers follow Olive’s journey from self‑deception to potential romance.
