Movies Released Out This Week: September 5–12, 2025 Releases You Can’t Miss

As summer fades into fall, the early September release calendar proves that studios aren’t slowing down — this week delivers a wide spectrum of films: horror, British period drama, anime epics, dystopian thrillers, and even a classic rock mockumentary reunion.

The first two weekends in September are shaping up as a box office pressure point, with multiple major titles landing almost simultaneously. Below are five of the biggest and most buzzed-about movies coming out this week that you’ll want to mark on your calendar.

The Conjuring: Last Rites – September 5

Cast: Vera Farmiga, Patrick Wilson
Director: Michael Chaves

The horror juggernaut returned with force. The Conjuring: Last Rites opened to $83 million domestically, more than doubling the first film’s $41.9M debut back in 2013. That makes it the biggest horror premiere of 2025 so far, and one of Warner Bros.’ strongest launches this year across any genre.

It’s also the franchise’s emotional capstone — a farewell to Ed and Lorraine Warren — and even with critics divided (56% on Rotten Tomatoes), the numbers prove the fanbase showed up in droves. Warner Bros. has now scored four #1 horror titles this year, cementing the Conjuring Universe’s dominance with nearly $2.5 billion in lifetime grosses.

Downton Abbey: The Grand Finale – September 12

Cast: Hugh Bonneville, Michelle Dockery, Elizabeth McGovern, Dominic West
Director: Simon Curtis

The Crawleys are back one final time. Downton Abbey: The Grand Finale picks up in 1930 as the family faces scandal, financial troubles, and a society in transition. Written by Julian Fellowes, the film gathers the beloved ensemble cast for a farewell, brimming with nostalgia and drama. In light of Dame Maggie Smith’s passing—it’s a deeply emotional send-off that underlines why the aristocratic saga has endured.

Spinal Tap II: The End Continues – September 12

Cast: Christopher Guest, Michael McKean, Harry Shearer, Rob Reiner
Director: Rob Reiner

Forty years after turning it up to 11, the loudest band in mockumentary history is back. Spinal Tap II reunites the fictional heavy metal trio for a chaotic final tour that skewers rock excess, aging musicianship, and the absurdities of fame. Expect deadpan interviews, outrageous set pieces, and cameos from real musicians paying tribute to the cult classic. More than just nostalgia, the sequel aims to remind audiences why This Is Spinal Tap became a comedy touchstone.

The Long Walk – September 12

Cast: Cooper Hoffman, David Jonsson, Colman Domingo, Isabela Merced
Director: Francis Lawrence

Stephen King’s first novel finally gets its big-screen moment. The Long Walk opened domestically on September 12, 2025, with $11.5 million across the USA. The Long Walk imagines a future where 50 teenage boys must walk without stopping, under penalty of death, until only one remains. Sparse in setting but heavy in dread, the adaptation pushes psychological horror as much as physical endurance.

Francis Lawrence (The Hunger Games: Catching Fire) brings intensity to King’s first novel, with a standout young cast anchoring the bleak premise. It’s a chilling meditation on survival, spectacle, and the human will to keep moving.

Demon Slayer: Infinity Castle – September 12 (Early Access from Sept 9)

Cast: Voice cast includes Natsuki Hanae, Akari Kitō, Hiro Shimono, Yoshitsugu Matsuoka
Director: Haruo Sotozaki

Anime’s biggest modern franchise reaches its most epic chapter yet. And Anime’s box office strength shows no signs of slowing. With early fan screenings beginning Sept 9, Demon Slayer: Infinity Castle brought in $70M for the biggest anime opening ever, proving there’s a huge emerging audience for the sub-genre.

Demon Slayer: Kimetsu no Yaiba – Infinity Castle adapts a climactic arc from the manga with stunning animation and explosive battles. Tanjiro, Nezuko, and their allies face the ultimate showdown against Muzan Kibutsuji inside a shape-shifting fortress. Beyond the spectacle, what’s making headlines is the release strategy: early access screenings begin September 9 for Crunchyroll’s premium fan tiers, a move that turns fandom loyalty into an opening-weekend event.

Why This September Weekend Is a Box Office Pressure Point

What makes this stretch so intriguing is the sheer variety: horror, period drama, comedy/music, dystopian thriller, and anime spectacle all landing within days of each other. That mix broadens choice for audiences but squeezes theaters and marketing campaigns into the same window.

Studios are leaning hard into event cinema—final chapters (The Conjuring, Downton Abbey), legacy revivals (Spinal Tap), and rabid fandoms (Demon Slayer). Add in Stephen King’s bleak Long Walk and you’ve got a lineup that demands attention across multiple quadrants.

The Takeaway

Whether you want chills, aristocratic melodrama, cult comedy, grim dystopia, or anime action, this week has it all. Theatrical windows may be shorter than ever, but these titles are designed for the big screen. So grab your popcorn—because movies coming out this week are shaping up to be some of the most interesting of the year.
