2026 has been a great year for book-to-screen adaptations, and the year's not over. Among the more anticipated titles set to arrive on the 2026 movie schedule is the film adaptation of Ali Hazelwood's mega-popular romance book, The Love Hypothesis. Those with a Prime Video subscription will be able to watch it beginning September 23. With less than a month to wait, we now have a proper trailer for the movie! Per PolygonThe Love Hypothesis started out as Star Wars fanfic, which was written by Ali Hazelwood under the pen name "Ever-So-Reylo." As you might be able to surmise from the non de plume, the fanfic centered on Star Wars characters Rey and Kylo Ren. As I'm sure you can tell from the trailer, The Love Hypothesis is not about Star Wars characters (it just started out that way). The story uses the fake-dating trope, and is centered on PhD student Olive and professor Dr. Adam Carlsen. Though their story starts out as a fake relationship things begin to get complicated, as fake relationships often do in these stories.The book arrived in 2021 and currently holds a 4.09 rating (out of 5) on Good Reads. That number is made even more impressive when we factor in that the novel has over 2 million ratings. Prime Video's adaptation of The Love Hypothesis is directed by Claire Scanion, and stars Lili Reinhart as Olive, and Tom Bateman as Adam Carlsen. Rachel Marsh plays Olive's best friend Ann, while Nicholas Duvernay plays Jeremy, the guy Ahn falls for.
