Summer is almost behind us, and for me, September officially marks the beginning of fall. As the days get shorter and the weather starts to cool, streaming services like Prime Video are already looking ahead to the colder months. That means swapping out some of those quintessential summer movies for cozier watches, autumnal favorites, and plenty of new movies and shows to settle in with as the seasons change.
Prime Video’s September 2026 lineup is now fully revealed, and I’ve rounded up the biggest releases worth keeping an eye on, from major new arrivals to some of the month’s most anticipated titles. That includes a new spinoff series set in the world of “Reacher,” an adrenaline-fueled action-thriller, and a romantic comedy based on Ali Hazelwood’s novel.
