Prime Video Drops First Look at ‘The Love Hypothesis’ with Lili Reinhart and Tom Bateman

Prime Video gave fans their first real taste of *The Love Hypothesis* this week, releasing a teaser trailer that brings Ali Hazelwood’s beloved bestseller to the screen. The film stars Lili Reinhart as Olive Smith, a Ph.D. student, opposite Tom Bateman as Dr. Adam Carlsen, the kind of intimidating professor who seems like he’d never crack a smile—until, of course, Olive comes along.

The minute-long teaser doesn’t waste any time getting to the good stuff. It kicks off with Olive’s impulsive decision to kiss Adam, a move designed to convince her best friend she’s finally moved on. But as anyone who’s read the book knows, that one kiss becomes a lot more complicated when real chemistry enters the equation.

What’s clever about the teaser is how it’s styled like a retro science instructional video—a nod to the story’s STEM-inspired DNA. The footage includes some of the moments book readers have been most eager to see, including that first kiss, witty back-and-forth between the leads, and a glimpse of the swoony “bridal lift” scene that had fans marking pages.

The cast also includes Rachel Marsh, Nicholas Duvernay, Jaboukie Young-White, and Arty Froushan. Sarah Rothschild penned the screenplay, while Claire Scanlon, who directed Set It Up, is behind the camera.

Prime Video unveiled the trailer at its inaugural Obsessed Fest event, with Reinhart and Bateman on hand to introduce it to an eager crowd. Online reactions have been strong, with viewers highlighting the palpable chemistry between the leads and praising how faithfully the film captures key moments from the novel.

Since its 2021 publication, The Love Hypothesis became a BookTok sensation and cemented itself as one of the most anticipated romance adaptations in years. The film arrives on Prime Video on September 23, 2026.
