The story follows Olive Smith, a biology PhD candidate who has completely given up on love. Then enters Dr. Adam Carlsen, a notorious professor known for his tyrannical reputation. Their fake relationship becomes the catalyst that throws both of their carefully constructed theories about love into complete chaos. Claire Scanlon, who directed Netflix’s beloved ‘Set It Up,’ will helm the project from a script by Sarah Rothschild.
Hazelwood’s novel spent 10 months dominating the New York Times bestseller list and broke out internationally in 40 countries. The book became Amazon’s Best Romance of the Year, cementing its status as a cultural phenomenon. This adaptation represents more than just another book-to-screen project. It signals Hollywood’s recognition of BookTok’s massive influence on contemporary entertainment.
Reinhart’s involvement extends far beyond just starring in the film. Through her production company Small Victory, she’s positioning herself as a major force in the romantic comedy renaissance. Her upcoming slate includes ‘American Sweatshop,’ ‘The Very Best People,’ and ‘Forbidden Fruits,’ proving she’s strategically building an empire in the genre that’s experiencing its biggest revival in decades. This project reunites her with Amazon MGM after their successful collaboration, setting the stage for what could become the streaming platform’s next major romantic franchise.
