Which blockbusters headline September streaming?
Disney and Pixar's "Toy Story 5" is the third highest-grossing film of 2026 so far, trailing only "Spider-Man: Brand New Day" and "The Odyssey." It lands on Disney+ near month's end and is expected to lift the wider "Toy Story" catalog.
Kane Parsons' horror smash "Backrooms" becomes available on HBO Max on Sept. 25. It is A24's highest-grossing title ever at $394 million worldwide. Variety's Owen Gleiberman praised its atmosphere and Chiwetel Ejiofor's central performance.
"The Mandalorian and Grogu," directed by Jon Favreau and starring Pedro Pascal, earned $345 million worldwide after an $81 million domestic opening. The Star Wars feature is now on Disney+, hoping for a streaming rebound. Paramount's "Scary Movie 6" (also billed as "Scary Movie") is on Paramount+ with an extended cut, reuniting Marlon Wayans, Shawn Wayans, Anna Faris, and Regina Hall.
What else joins the best movies new streaming list?
Beyond the headliners, September's slate is deep. "Supergirl" arrives on HBO Max on Sept. 10, with an ASL version also planned. Tyler Perry's "Why Did I Get Married Again?" debuts on Netflix on Sept. 9, while Jacob Tremblay leads Netflix's "Unabomber" on Sept. 25 opposite Russell Crowe and Shailene Woodley.
Prime Video adds Gal Gadot's real-time thriller "The Runner" (Sept. 2) and the Lili Reinhart-Tom Bateman romance "The Love Hypothesis" (Sept. 23). Hulu gets "100 Nights of Hero" on Sept. 18 and the water-polo camp horror "The Plague" on Sept. 25. HBO Max also streams David Mackenzie's London thriller "Fuze" on Sept. 4.
Netflix further stacks the month with "Call My Agent! The Movie" (Sept. 10), Adam Shankman's "Stop That Train!" starring RuPaul (Sept. 20), the AI documentary "The AI Doc: Or How I Became an Apocaloptimist" (Sept. 15), Maitreyi Ramakrishnan's "Best of the Best" (Sept. 18), and Chris Smith's true-crime doc "The Widower: 'Til Death Do Us Part" (Sept. 30).
Why does this September slate matter for streamers?
After a huge summer at the box office, these debuts matter because they move proven theatrical hits and fresh originals onto the services people actually open nightly. Families get "Toy Story 5," horror fans get "Backrooms," and franchise viewers can revisit "The Mandalorian and Grogu" without leaving home.
If you are prioritizing watchlists, start with the four title-card names, then fill gaps with platform exclusives such as "The Runner," "Supergirl," or "Why Did I Get Married Again?" That mix is why Variety's September guide is a practical map for the fall streaming corridor.
