17 Best Movies New to Streaming in September: ‘Toy Story 5,’ ‘Backrooms,’ ’Scary Movie 6,’ ’The Mandalorian and Grogu’

Labor Day Weekend brings to a close the summer movie season, which became one of the biggest on record thanks to the mega-blockbusters “The Odyssey” and “Spider-Man: Brand New Day.” But the season is just getting started on streaming platforms as some of the summer’s buzziest titles make their streaming debuts to kick off the fall movie corridor.

“Toy Story 5” is the third highest-grossing movie of the year with $1.13 billion and should prove to be a streaming mega-hit when it arrives on Disney+ near the end of the month. Expect the whole “Toy Story” animated franchise to get a streaming lift as a result. A24’s horror hit “Backrooms,” which became the studio’s highest-grossing title in history this summer, should also prove a streaming hit when it lands on HBO Max. Meanwhile, the “Star Wars” misfire “The Mandalorian and Grogu” hopes to rebound on Disney+ after stumbling in theaters. The movie is now available to stream, as is Paramount’s “Scary Movie 6.”

Check out a full rundown below of the biggest new titles to streaming in September.

• Toy Story 5 (Sept. 23 on Disney+)

  

  Disney and Pixar’s animated blockbuster “Toy Story 5” arrives on Disney+ this month after earning $1.13 billion and counting at the summer box office, which makes it the third highest-grossing movie of 2026 so far (trailing “Spider-Man: Brand New Day” and “The Odyssey”). The sequel was also named one of Variety’s best movies of the year so far: “It escalates in delight (the climactic wedding ceremony must be seen to be believed), but it also has moments that hit you like a gut punch. The message is: Slow down, be real and play. The fun you take is equal to the fun you make.”

• Backrooms (Sept. 25 on HBO Max)

  

  Kane Parsons’ horror smash “Backrooms” arrives on HBO Max this month after becoming A24’s highest-grossing movie of all time with $394 million at the worldwide box office. “As an atmospheric freakout, ‘Backrooms’ is extraordinarily effective,” Variety‘s chief film critic Owen Gleiberman wrote in his positive review, noting that Chiwetel Ejiofor was “the perfect presence to have at the center.” He also compared Parsons’ fixation for mood and “cosmic sound design” to the late David Lynch.

• The Mandalorian and Grogu (Disney+)

  

  “The Mandalorian and Grogu” suffered at the summer box office with an $81 million domestic debut, an underwhelming start for a “Star Wars” movie. The film went on to earn $345 million worldwide, far below the billion-dollar grosses of the previous “Star Wars” film releases “The Rise of Skywalker” and “The Last Jedi.” But can “The Mandalorian and Grogu” rebound on streaming? Directed by Jon Favreau, the movie follows bounty hunter Din Djarin (Pedro Pascal) and his apprentice, Grogu, as they’re recruited by officer Colonel Ward (Sigourney Weaver) to aid the New Republic. The unlikely duo must rescue the heir to Jabba the Hutt, Rotta the Hutt (voiced by “The Bear’s” Jeremy Allen White), in order to track down an Imperial leader.
  

• Scary Movie (Paramount+) 

  

  “Scary Movie,” also known as “Scary Movie 6,” is now streaming on Paramount+ after delighting the box office with a strong $231 million worldwide. An extended cut of the movie is also now streaming on the same platform. Returning cast members include Marlon Wayans (Shorty Meeks), Shawn Wayans (Ray), Anna Faris (Cindy Campbell) and Regina Hall (Brenda Meeks). Faris and Hall reprised their roles after neither appeared in “Scary Movie 5.”
