Toy Story 5, Backrooms, and Five Other September Streams

September used to be when streamers dumped library filler and called it a “new month.” This one is messier. Variety’s September 2026 streaming rundown is built around theatrical leftovers that actually made money, plus a couple of oddities that did not. That is a better shopping list than another reminder that Aliens is on Netflix again.

We already did the late-August streaming pile and a fall theatrical list that ignored the giant sequels. This is the couch version of September: what showed up at home this month, what date it lands, and whether it deserves the remote.

Toy Story 5 (September 23, Disney+)

Pixar’s sequel took $1.13 billion and sits third for 2026 so far, behind Spider-Man: Brand New Day and The Odyssey. Variety already had it on the midyear best list, which is not a sentence you get to write about every billion-dollar cartoon. The note they quote is the one that matters for a living-room replay: it escalates, then it sucker-punches you, and the wedding scene is the part people will rewatch on a Tuesday.

If you have kids, you are seeing this whether I recommend it or not. If you do not, this is still the rare franchise entry that is doing theme work instead of product placement. The rest of the Toy Story catalog will get a bump the same week. That is fine. Start with 5, then decide if you need the origin story again.

Backrooms (September 25, HBO Max)

A24’s summer horror hit is, per Variety, the studio’s highest-grossing title. Chiwetel Ejiofor is the face in the stills. The internet “backrooms” meme was a yellow-wallpaper creepypasta; turning that into a theatrical event that actually sold tickets is the part I did not expect.

Watch this before someone spoils the geography. Liminal-space horror dies in a group chat. It also dies on a phone. Put it on a decent display and keep the lights low. If you bounced off A24’s more talky prestige horror, this is the one that played like a crowd movie.

100 Nights of Hero (September 18, Hulu)

Julia Jackman adapted Isabel Greenberg’s graphic novel. The cast is greedy in a good way: Maika Monroe, Emma Corrin, Nicholas Galitzine, plus Charli XCX, Richard E. Grant, and Felicity Jones. Variety’s capsule is a fidelity wager: neglectful husband leaves, maid Hero and wife Cherry have to outlast a visitor who is not making a social call.

This is the opposite of Toy Story 5. It is the movie you put on when the house is quiet and you want costume, story, and a little danger. Graphic-novel adaptations usually flatten. The names attached here suggest they at least tried not to.

Best of the Best (September 18, Netflix)

Lionsgate/Netflix, Maitreyi Ramakrishnan and Priyanka Kedia. Variety files it in the September dump without a full critical case, which is honest. I am including it because September Netflix is usually either a true-crime slab or a rom-com that forgot to write a second act. A teen/young-adult sports-or-status comedy with Ramakrishnan is at least a change of pulse.

If it is slight, it is 100 minutes you can abandon. That is a feature. Not every night needs The Odyssey.

The Plague (September 25, Hulu)

Water polo camp. New kid. Cruel peer. A rumor that another boy has “the plague.” Joel Edgerton in the adult-shaped hole. Variety calls it unconventional horror, which often means “slow and mean.” That is the lane I want in late September, when jump-scare trailers have been yelling since June.

Camp movies live or die on whether the kids feel like a closed society. If the clips are any guide, they do. Pair it with Backrooms only if you enjoy sleeping badly. I would not stack them.

The AI Doc: Or How I Became an Apocaloptimist (September 15, Netflix)

The title is doing too much, which is usually a tell. I still have it on the list because September is full of fiction about machines and short on people admitting what they actually built. A documentary with a joke subtitle is easier to finish than another scripted thinkpiece.

Go in with a filter. Docs that brand themselves as “apocaloptimist” want a tidy ending. Pause if it starts selling you a product. Use it as a palate cleanser between the Pixar replay and the A24 maze.

What I am not pushing

The Mandalorian and Grogu is on Disney+ now. Variety calls the theatrical run a misfire and hopes streaming is a rebound. Maybe. I would not use a weeknight on a Star Wars apology tour unless you already liked the show.

Scary Movie 6 (billed as Scary Movie) is on Paramount+ with an extended cut, $231 million worldwide, Anna Faris and Regina Hall back. That is a party movie. It is not a “you should study this” movie. If you have a group, it wins. If you are alone, you will notice the air going out of the jokes.

Netflix’s Unabomber, with Jacob Tremblay and Russell Crowe, lands September 25. I am leaving it off the watch pile on purpose. There is enough September without a domestic-terrorism biopic as comfort viewing.

Mayday hit Apple TV on September 4. We already reviewed Reynolds and Branagh. If you skipped theaters, that is the better adult ticket than most of the catalog Gizmodo listed (Get Out, Aliens, 17 Again). Those films are good. They are not news.

Digital Spy is also high on Guy Ritchie’s In the Grey (Henry Cavill, Eiza González, Jake Gyllenhaal, Rosamund Pike). If it hits your platform this month, it is the stylish thriller slot. I am waiting for a date that is not a shrug.

Why the Variety list is the useful one this month

Gizmodo’s September menu is a genre closet: 17 Again, About Time, Alien and Aliens, Get Out, a Ninja Turtles documentary. Those are good Friday-night defaults. They are also available most months if you hunt. Variety is tracking titles that just left multiplexes or just got a date. That is the incremental list.

Toy Story 5 at $1.13 billion is not a secret. The useful detail is the date: September 23 on Disney+, late enough that you should not pay premium VOD the week before unless you have a birthday party. Backrooms on the 25th is the other half of that weekend. A24 does not always land on HBO Max this fast. If you care about watching horror before the discourse calcifies, that Friday is the appointment.

100 Nights of Hero and The Plague sharing Hulu mid-to-late month is a nicer pairing than it looks. One is costumes and a wager. One is boys and a rumor. Both are mid-budget, which is the species we already said theaters keep losing. Streaming is where those films go to finish earning. You can argue that is sad. You can also press play.

Best of the Best on Netflix the same day as 100 Nights is the fork: noise versus craft. I would not try both in one night. Netflix will autoplay something worse if you hesitate.

Scary Movie’s $231 million and the Faris/Hall return are a studio victory lap. Extended cuts of spoof movies are rarely tighter. If you stream it, use the theatrical version first. The Mandalorian film is the opposite problem: a theatrical shrug hoping the living room is kinder. Sometimes that works (Mutiny knew what it was; we said so in August). Star Wars apologies usually do not.

How to actually watch the month

Pick two new titles and one comfort replay, not seven tabs. A sane September:

• Family night: Toy Story 5 on the 23rd.
• One horror: either Backrooms or The Plague, not both in 48 hours.
• One mid-size: 100 Nights of Hero if you want craft, Best of the Best if you want noise.

Dates worth putting on a calendar, not a vibe:

Date	Title	Where
Sept 4	Mayday	Apple TV (already reviewed)
Sept 15	The AI Doc	Netflix
Sept 18	100 Nights of Hero	Hulu
Sept 18	Best of the Best	Netflix
Sept 23	Toy Story 5	Disney+
Sept 25	Backrooms	HBO Max
Sept 25	The Plague	Hulu

If you only remember two rows, remember the 23rd and the 25th. That weekend is the reason September is not a library dump. Digital Spy’s Cavill/Ritchie thriller can wait until a platform prints a day.

Catalog titles are for rain. New streams are for the night they arrive, because the group chat will spoil Backrooms by Monday. We already used August to clear the leftover pile. This month is shorter on purpose.

I would skip premium VOD on Toy Story 5 unless a child is counting sleeps. Disney+ on the 23rd is the sane buy. Backrooms is the opposite: if you care, watch close to the 25th, before stills circulate. 100 Nights of Hero can wait a weekend; costume films do not spoil as fast as maze films. The Plague I would not watch with kids in the house, even older kids. Water polo camp cruelty is a specific mood.

If September is already full, the minimum viable month is Toy Story plus one horror. Everything else is optional, including this list. If you already burned weekends on Telluride coverage, skip the documentary and the spoof. You have seen enough movies. Two good ones beat a completed spreadsheet. I am not ranking Cavill until there is a date. Lists that pretend every title is equal are how you watch nothing. Pay for one night out if you want popcorn; save the 23rd and 25th for the couch. That is the month.

That leaves you with a weekend and no sense that you “fell behind on streaming,” which is not a real obligation. Theaters still have the fall calendar we already flagged. Home video is catching the summer that printed money. Start with the one that printed $1.13 billion, then decide whether you want to get lost on purpose.
